Apple Addresses Two Actively Exploited Zero-Day Security Flaws


Following confirmation that two previously unknown security flaws had been actively exploited in the wild on Friday, Apple rolled out a series of security updates across its entire software ecosystem to address this issue, further demonstrating the continued use of high-end exploit chains against some targets. This is a major security update that is being released by Apple today across a wide range of iOS, iPadOS, macOS, watchOS, tvOS, visionOS, and the Safari browser. This fix addresses flaws that could have led attackers to execute malicious code in the past using specially crafted web content.


There are a number of vulnerabilities that are reminiscent of one of the ones Google patched earlier this week in Chrome, highlighting cross-platform vulnerability within shared graphics components. A report released by Apple indicated that at least one of the flaws may have been exploited as part of what it described as an "extremely sophisticated attack" targeting individuals who were running older versions of iOS before iOS 26, indicating that rather than an opportunistic abuse, this was a targeted exploitation campaign. 

Using a coordinated effort between Apple Security Engineering and Architecture and Google's Threat Analysis Group, the vulnerabilities were identified as CVE-2025-14174, a high severity memory corruption flaw, and as CVE-2025-43529, a use-after-free flaw. The two vulnerabilities were tracked as CVE-2025-43529, a use-after-free bug. 

In response to advanced threat activity, major vendors are continuing to collaborate together. Separately, Apple has released a new round of emergency patches after confirming that two more vulnerabilities have also been exploited in a real-world attack in a separate advisory. 

Apple has released a new update to address the flaws that could allow attackers to gain deeper control over their affected devices under carefully crafted conditions, and this update is applicable to iOS, iPadOS, macOS Sequoia, tvOS, and visionOS. 

A memory corruption issue in Apple's Core Audio framework has led to an issue named CVE-2025-31200 which could result in arbitrary code execution on a device when it processes a specially designed audio stream embedded within a malicious media file. The second issue is CVE-2025-31201. This flaw affects Apple's RPAC component, which could be exploited by an attacker with existing read and write capabilities in order to bypass the protections for Pointer Authentication.

In an attempt to mitigate the risks, Apple said it strengthened bounds checks and removed the vulnerable code path altogether. According to Apple's engineers, Google's Threat Analysis Group as well as the company's own engineers were the ones who identified the Core Audio vulnerability. According to the company's earlier disclosures, the bugs have been leveraged to launch what it calls "extremely sophisticated" attacks targeting a very specific group of iOS users. 

With the latest fix from Apple, the number of zero-day vulnerabilities Apple has patched in the past year has reached five, following earlier updates addressing actively exploited flaws in Core Media, Accessibility, and WebKit—a combination of high-risk issues that indicates a sustained focus by advanced threat actors on Apple's software stack, demonstrating that Apple's software stack has been the target of sophisticated attack actors. 

The company claims the vulnerabilities have been addressed across its latest software releases, including iOS 26.2, iOS and iPad OS 18.7.3, macOS Tahoe 26.2, tvOS 26.2, watchOS 26.2, visionOS 26.2, and Safari 26.2, making sure that both current and legacy platforms are protected from these threats.

Following the disclosure, Google quietly patched a previously undisclosed Chrome zero-day that had been labelled only as a high-severity issue "under coordination" earlier in the week, which was close in nature. After updating its advisory to CVE-2025-14174, Google confirmed that the flaw is an out-of-bounds memory access bug in the ANGLE graphics layer, which was the same issue that was addressed by Apple earlier this week. 

It indicates that Google and Apple handled vulnerabilities together in a coordinated manner. In the absence of further technical insight into the attacks themselves, Apple has refused to provide any further technical information, other than to note that the attacks were directed at a single group of individuals running older versions of iOS prior to iOS 26, which can be correlated with using exploits that are spyware-grade in nature. 

Since the problems both originate in WebKit, the browser engine that runs all iOS browsers, including Chrome, the researchers believe the activity represents a narrowly targeted campaign rather than an indiscriminate exploitation of the platform. 

Even though Apple emphasised that these attacks were targeted and very specific, the company strongly urged its users to update their operating systems without delay in order to prevent any further damage to their systems. 

Apple has patched seven zero-day vulnerabilities during 2025 with these updates. There have been a number of exploits that have been addressed in the wild throughout the year, from January and February until April, as well as a noteworthy backport that was implemented in September that provided protection against CVE-2025-43300 on older iPhone and iPad models still running iOS or iOSOS 15 and 16.

Apple's platforms have increasingly been discovered to be a high-value target for well-resourced threat actors, with the capability of exploiting browser and system weaknesses in a way that allows them to reach carefully selected victims using a chain of attacks on the platforms. 

It is evident that the company's rapid patching cadence, along with coordinated efforts with external researchers, indicates the company's maturing response to advanced exploitation; however, the frequency of zero-day fixes this year highlights the importance of timely updates across all supported devices in order to safeguard consumers.

Specifically, security experts recommend that users, especially those who perform high risk functions like journalists, executives, and public figures, enable automatic updates, limit the amount of untrusted web content they view, and review device security settings in order to reduce potential attack surfaces. 

Enterprises that manage Apple hardware at scale should also accelerate patch deployments and keep an eye out for signs of compromise associated with WebKit-based attacks. A growing number of targeted surveillance tools and commercial spyware continue to emerge, and Apple’s latest fixes serve to remind us of the fact that platform security is more of a process than it is a static guarantee. 

For a company to stay ahead of sophisticated adversaries, collaboration, transparency, and user awareness are increasingly critical to ensuring platform security.

Ivanti Flags Critical Endpoint Manager Flaw Allowing Remote Code Execution

 

Ivanti is urging customers to quickly patch a critical vulnerability in its Endpoint Manager (EPM) product that could let remote attackers execute arbitrary JavaScript in administrator sessions through low-complexity cross-site scripting (XSS) attacks.The issue, tracked as CVE-2025-10573, affects the EPM web service and can be abused without authentication, but does require some user interaction to trigger.

The flaw stems from how Ivanti EPM handles managed endpoints presented to the primary web service. According to Rapid7 researcher Ryan Emmons, an attacker with unauthenticated access to the EPM web interface can register bogus managed endpoints and inject malicious JavaScript into the administrator dashboard. Once an EPM administrator views a poisoned dashboard widget as part of routine use, the injected code executes in the browser, allowing the attacker to hijack the admin session and act with their privileges.

Patch availability and exposure

Ivanti has released EPM 2024 SU4 SR1 to remediate CVE-2025-10573 and recommends customers install this update as soon as possible. The company stressed that EPM is designed to operate behind perimeter defenses and not be directly exposed to the public internet, which should lower practical risk where deployments follow guidance.However, data from the Shadowserver Foundation shows hundreds of Ivanti EPM instances reachable online, with the highest counts in the United States, Germany, and Japan, significantly increasing potential attack surface for those organizations.

Alongside the critical bug, Ivanti shipped fixes for three other high‑severity vulnerabilities affecting EPM, including CVE-2025-13659 and CVE-2025-13662. These two issues could also enable unauthenticated remote attackers to execute arbitrary code on vulnerable systems under certain conditions. Successful exploitation of the newly disclosed high‑severity flaws requires user interaction and either connecting to an untrusted core server or importing untrusted configuration files, which slightly raises the bar for real-world attacks.

Threat landscape and prior exploitation

Ivanti stated there is currently no evidence that any of the newly patched flaws have been exploited in the wild and credited its responsible disclosure program for bringing them to light. Nonetheless, EPM vulnerabilities have been frequent targets, and U.S. Cybersecurity and Infrastructure Security Agency (CISA) has repeatedly added Ivanti EPM bugs to its catalog of exploited vulnerabilities. In 2024, CISA ordered federal agencies to urgently patch multiple Ivanti EPM issues, including three critical flaws flagged in March and another actively exploited vulnerability mandated for remediation in October.

New SVG-Based Clickjacking Technique Exposes Cross-Origin Data Through CSS Filters

 

Security researcher Lyra Rebane has developed a new type of clickjacking attack that cleverly exploits Scalable Vector Graphics (SVG) and Cascading Style Sheets (CSS) to bypass traditional web protections.

Rebane first showcased this discovery during BSides Tallinn in October and has since released a technical breakdown of the method. The attack takes advantage of a little-known behavior where SVG filters can inadvertently expose cross-origin information—directly undermining the web’s same-origin policy.

Clickjacking, also known as a user interface redress attack, involves deceiving users into performing unintended actions by visually manipulating interface elements. The concept, introduced in 2008 by security researchers Jeremiah Grossman and Robert Hansen, was originally described as a technique for redirecting mouse clicks to malicious targets such as hidden buttons or form inputs.

Over the years, browsers have implemented numerous defenses to prevent such attacks. OWASP highlights common safeguards such as blocking page rendering within frames via X-Frame-Options or CSP frame-ancestors, limiting cookie access inside frames, and using JavaScript frame-busting scripts. Even with these protections, new variants continue to appear—most recently, last year’s cross-window forgery technique.

Rebane’s discovery began while she was experimenting with recreating Apple’s Liquid Glass distortion effect using SVG filters and CSS. Once she successfully replicated the effect, she noticed that when embedded inside an iframe, her SVG/CSS implementation could detect pixel data from the page beneath it—effectively accessing information from another origin.

She told The Register that previous attempts using SVG for cross-origin attacks exist, citing Paul Stone’s “Perfect Pixel Timing Attacks With HTML” and Ron Masas’s “The Human Side Channel”. But, as Rebane stated, "I don't think anyone else has run logic on cross-origin data the way I have."

Her write-up details how she used SVG filters to construct logic gates capable of processing webpage pixels using arbitrary computation—enabling a clickjacking method that would be extremely difficult to achieve with other tools.

According to Rebane, "By using feBlend and feComposite, we can recreate all logic gates and make SVG filters functionally complete. This means that we can program anything we want, as long as it is not timing-based and doesn't take up too many resources."

To demonstrate the risks, Rebane created a proof-of-concept that extracts text from Google Docs. Her attack overlays a “Generate Document” button on a popup. When clicked, the underlying script identifies the popup and shows a CAPTCHA-style textbox. Once submitted, the attacker-controlled interface secretly feeds a suggested Google Docs file name into a hidden textbox. While typical framing restrictions would prevent this, Google Docs allows itself to be embedded, making the attack viable.

Rebane noted that this is common among services intended for embedding—such as YouTube videos, social widgets, maps, payment systems, comment modules, and advertisements. Some services also unintentionally permit framing by failing to include protective headers, which is frequently seen in API endpoints.

Beyond iframe scenarios, Rebane explained that the technique can also be adapted for sites vulnerable to HTML injection.

She said, "There's a vulnerability class known as XSS which involves injecting HTML on websites through various means to execute malicious JavaScript." With CSP now blocking many forms of unsafe JavaScript, attackers look for alternatives. In such cases, "CSS is the next best thing to use, and it can be used for many kinds of interesting attacks," she added, arguing that CSS itself behaves like a programming language. "SVG clickjacking is one of the many attacks that could be used there."

Although the method does not fundamentally overhaul existing web security principles, it significantly lowers the complexity required to execute advanced attack chains.

Google awarded Rebane a $3,133.70 bug bounty for reporting the flaw. She noted that the issue remains unresolved and may not even be classified as a browser bug, adding that Firefox and other browsers are affected as well.

Rebane also pointed out potential mitigations—highlighting the Intersection Observer v2 API, which can detect when an SVG filter is positioned above an iframe.

Google has yet to comment on the matter. A related Chromium bug originating from earlier timing attacks has been closed with a “won’t fix” status.

React2Shell Exploited Within Hours as Firms Rush to Patch

 

Two hacking groups linked to China have started exploiting a major security flaw in React Server Components (RSC) only hours after the vulnerability became public. 

The flaw, tracked as CVE-2025-55182 and widely called React2Shell, allows attackers to gain unauthenticated remote code execution, potentially giving them full control over vulnerable servers. 

The security bug has a maximum CVSS score of 10.0, which represents the highest level of severity. It has been fixed in React versions 19.0.1, 19.1.2 and 19.2.1, and developers are being urged to update immediately. According to a report shared by Amazon Web Services, two China-nexus groups named Earth Lamia and Jackpot Panda were seen attempting to exploit the flaw through AWS honeypot systems. 

AWS said the activity was coming from infrastructure previously tied to state-linked cyber actors. Earth Lamia has previously targeted organizations across financial services, logistics, retail, IT, universities and government sectors across Latin America, the Middle East and Southeast Asia. 

Jackpot Panda has mainly focused on sectors connected to online gambling in East and Southeast Asia and has used supply chain attacks to gain access. The group was tied to the 2022 compromise of the Comm100 chat application and has used trojanized installers to spread malware. 

AWS also noted that attackers have been exploiting the React vulnerability alongside older bugs, including flaws in NUUO camera systems. Early attacks have attempted to run discovery commands, create files and read sensitive information from servers. 

Security researchers say the trend shows how fast attackers now operate: they monitor new vulnerability announcements and add exploits to their scanning tools immediately to increase their chances of finding unpatched systems. 

A brief global outage at Cloudflare this week added to industry concern. Cloudflare confirmed that a change to its Web Application Firewall, introduced to help protect customers from the newly disclosed React flaw, caused disruption that led many websites to return “500 Internal Server Error” messages. 

The company stressed that the outage was not the result of a cyberattack. The scale of the React vulnerability is a major concern because millions of websites rely on React and Next.js, including large brands such as Airbnb and Netflix. 

Security researchers estimate that about 39 percent of cloud environments contain vulnerable React components. A working proof-of-concept exploit is already available on GitHub, raising fears of mass exploitation. Experts warn that even projects that do not intentionally use server-side functions may still be exposed because the affected components can remain enabled by default. 

Cybersecurity firms and cloud providers are urging organizations to take action immediately: 


  1. Apply official patches for React, Next.js and related RSC frameworks.
  2. Enable updated Web Application Firewall rules from providers including AWS, Cloudflare, Google Cloud, Akamai and Vercel.
  3. Review logs for signs of compromise, including suspicious file creation, attempts to read sensitive data or reconnaissance behavior.

Although widespread exploitation has not yet been confirmed publicly, experts warn that attackers are already scanning the internet at scale. 

Critical Vulnerabilities Found in React Server Components and Next.js


Open in the wild flaw

The US Cybersecurity and Infrastructure Security Agency (CISA) added a critical security flaw affecting React Server Components (RSC) to its Known Exploited Vulnerabilities (KEV) catalog after exploitation in the wild.

The flaw CVE-2025-55182 (CVSS score: 10.0) or React2Shell hints towards a remote code execution (RCE) that can be triggered by an illicit threat actor without needing any setup. 

Remote code execution 

According to the CISA advisory, "Meta React Server Components contains a remote coThe incident surfaced when Amazon said it found attack attempts from infrastructure related to Chinese hacking groupsde execution vulnerability that could allow unauthenticated remote code execution by exploiting a flaw in how React decodes payloads sent to React Server Function endpoints."

The problem comes from unsafe deserialization in the library's Flight protocol, which React uses to communicate between a client and server. It results in a case where an unauthorised, remote hacker can deploy arbitrary commands on the server by sending specially tailored HTTP requests. The conversion of text into objects is considered a dangerous class of software vulnerability. 

About the flaw

 "The React2Shell vulnerability resides in the react-server package, specifically in how it parses object references during deserialization," said Martin Zugec, technical solutions director at Bitdefender.

The incident surfaced when Amazon said it found attack attempts from infrastructure related to Chinese hacking groups such as Jackpot Panda and Earth Lamia. "Within hours of the public disclosure of CVE-2025-55182 (React2Shell) on December 3, 2025, Amazon threat intelligence teams observed active exploitation attempts by multiple China state-nexus threat groups, including Earth Lamia and Jackpot Panda," AWS said.

Attack tactic 

Few attacks deployed cryptocurrency miners and ran "cheap math" PowerShell commands for successful exploitation. After that, it dropped in-memory downloaders capable of taking out extra payload from a remote server.

According to Censys, an attack surface management platform, 2.15 million cases of internet-facing services may be affected by this flaw. This includes leaked web services via React Server Components and leaked cases of frameworks like RedwoodSDK, React Router, Waku, and Next.js.

According to data shared by attack surface management platform Censys, there are about 2.15 million instances of internet-facing services that may be affected by this vulnerability. This comprises exposed web services using React Server Components and exposed instances of frameworks such as Next.js, Waku, React Router, and RedwoodSDK.


Microsoft Quietly Changes Windows Shortcut Handling After Dangerous Zero-day Abuse

 



Microsoft has changed how Windows displays information inside shortcut files after researchers confirmed that multiple hacking groups were exploiting a long-standing weakness in Windows Shell Link (.lnk) files to spread malware in real attacks.

The vulnerability, CVE-2025-9491, pertains to how Windows accesses and displays the "Target" field of a shortcut file. The attackers found that they could fill the Target field with big sets of blank spaces, followed by malicious commands. When a user looks at a file's properties, Windows only displays the first part of that field. The malicious command remains hidden behind whitespace, making the shortcut seem innocuous.

These types of shortcuts are usually distributed inside ZIP folders or other similar archives, since many email services block .lnk files outright. The attack relies on persuasion: Victims must willingly open the shortcut for the malware to gain an entry point on the system. When opened, the hidden command can install additional tools or create persistence.


Active Exploitation by Multiple Threat Groups

Trend Micro researchers documented in early 2025 that this trick was already being used broadly. Several state-backed groups and financially motivated actors had adopted the method to deliver a range of malware families, from remote access trojans to banking trojans. Later, Arctic Wolf Labs also observed attempts to use the same technique against diplomats in parts of Europe, where attackers used the disguised shortcut files to drop remote access malware.

The campaigns followed a familiar pattern. Victims received a compressed folder containing what looked like a legitimate document or utility. Inside sat a shortcut that looked ordinary but actually executed a concealed command once it was opened.


Microsoft introduces a quiet mitigation

Although Microsoft first said the bug did not meet the criteria for out-of-band servicing because it required user interaction, the company nonetheless issued a silent fix via standard Windows patching. With the patches in place, Windows now displays the full Target field in a shortcut's properties window instead of truncating the display after about 260 characters.

This adjustment does not automatically remove malicious arguments inside a shortcut, nor does it pop up with a special warning when an unusually long command is present. It merely provides full visibility to users, which may make suspicious content more easily identifiable for the more cautious users.

When questioned about the reason for the change, Microsoft repeated its long-held guidance: users shouldn't open files from unknown sources and should pay attention to its built-in security warnings.


Independent patch offers stricter safeguards

Because Microsoft's update is more a matter of visibility than enforcement, ACROS Security has issued an unofficial micropatch via its 0patch service. The update its team released limits the length of Target fields and pops up a warning before allowing a potentially suspicious shortcut to open. This more strict treatment, according to the group, would block the vast majority of malicious shortcuts seen in the wild.

This unofficial patch is now available to 0patch customers using various versions of Windows, including editions that are no longer officially supported.


How users can protect themselves

Users and organizations can minimize the risk by refraining from taking shortcuts coming from unfamiliar sources, especially those that are wrapped inside compressed folders. Security teams are encouraged to ensure Windows systems are fully updated, apply endpoint protection tools, and treat unsolicited attachments with care. Training users to inspect file properties and avoid launching unexpected shortcut files is also a top priority.

However, as the exploitation of CVE-2025-9491 continues to manifest in targeted attacks, the updated Windows behavior, user awareness, and security controls are layered together for the best defense for now. 

65% of Top AI Companies Leak Secrets on GitHub

 

Leading AI companies continue to face significant cybersecurity challenges, particularly in protecting sensitive information, as highlighted in recent research from Wiz. The study focused on the Forbes top 50 AI firms, revealing that 65% of them were found to be leaking verified secrets—such as API keys, tokens, and credentials—on public GitHub repositories. 

These leaks often occurred in places not easily accessible to standard security scanners, including deleted forks, developer repositories, and GitHub gists, indicating a deeper and more persistent problem than surface-level exposure. Wiz's approach to uncovering these leaks involved a framework called "Depth, Perimeter, and Coverage." Depth allowed researchers to look beyond just the main repositories, reaching into less visible parts of the codebase. 

Perimeter expanded the search to contributors and organization members, recognizing that individuals could inadvertently upload company-related secrets to their own public spaces. Coverage ensured that new types of secrets, such as those used by AI-specific platforms like Tavily, Langchain, Cohere, and Pinecone, were included in the scan, which many traditional tools overlook.

The findings show that despite being leaders in cutting-edge technology, these AI companies have not adequately addressed basic security hygiene. The researchers disclosed the discovered leaks to the affected organisations, but nearly half of these notifications either failed to reach the intended recipients, were ignored, or received no actionable response, underscoring the lack of dedicated channels for vulnerability disclosure.

Security Tips 

Wiz recommends several essential security measures for all organisations, regardless of size. First, deploying robust secret scanning should be a mandatory practice to proactively identify and remove sensitive information from codebases. Second, companies should prioritise the detection of their own unique secret formats, especially if they are new or specific to their operations. Engaging vendors and the open source community to support the detection of these formats is also advised.

Finally, establishing a clear and accessible disclosure protocol is crucial. Having a dedicated channel for reporting vulnerabilities and leaks enables faster remediation and better coordination between researchers and organisations, minimising potential damage from exposure. The research serves as a stark reminder that even the most advanced companies must not overlook fundamental cybersecurity practices to safeguard sensitive data and maintain trust in the rapidly evolving AI landscape.

Should You Still Trust Your Router? What Users Need to Know and How to Secure Home Wi-Fi today

 



Public discussion in the United States has intensified around one of the country’s most widely purchased home router brands after reports suggested that federal agencies are considering restrictions on future sales. The conversation stems from concerns about potential national security risks and the possibility of foreign influence in hardware design or data handling. While the company firmly denies these allegations, the ongoing scrutiny has encouraged many users to reassess the safety of their home Wi-Fi setup and understand how to better protect their networks.


Why the issue surfaced

The debate began when officials started examining whether equipment manufactured by the company could expose American networks to security risks. Investigators reportedly focused on the firm’s origins and questioned whether foreign jurisdictions could exert influence over product development or data processes.

The company has rejected these claims, saying its design, security functions, and oversight structures operate independently and that its leadership teams within the United States manage core product decisions. It maintains that no government has the ability to access or manipulate its systems.


Common router vulnerabilities users should understand

Even without the broader policy debate, home routers are frequently targeted by attackers, often through well-known weaknesses:

Hardware-level risks. In rare cases, security issues can originate in the physical components themselves. Malicious implants or flawed chips can give attackers a hidden entry point that is difficult for users to detect without specialized tools.

Unpatched security gaps. Zero-day vulnerabilities are flaws discovered by attackers before the manufacturer has prepared a fix. Some older or discontinued models may never receive patches, leaving users exposed for the long term.

Outdated firmware. Firmware updates serve the same purpose as software updates on phones and computers. Without them, routers miss critical security improvements and remain vulnerable to known exploits.

Botnets. Compromised routers are often absorbed into large collections of infected devices. These groups of hijacked systems are then directed to launch attacks, spread malware, or steal information.

Weak login credentials. Many intrusions occur simply because users keep the default administrator username and password. Attackers run automated tools that test the most common combinations in an attempt to break in.

Exposed remote settings. Some routers allow remote control panels to be accessed from outside the home network. If these remain active or are protected with simple passwords, attackers can quietly enter the system.

Outdated Wi-Fi encryption. Older wireless standards are easy for attackers to crack. Weak encryption allows outsiders to intercept traffic or join the network without permission.


How to strengthen your home network today

Any user can substantially improve their router’s security by following a few essential steps:

1. Change default passwords immediately. Use strong, unique credentials for both the router’s control panel and the Wi-Fi network.

2. Check for firmware updates regularly. Install every available update. If your device no longer receives support, replacement is advisable.

3. Enable the built-in firewall. It acts as the first barrier between your home network and outside threats.

4. Turn off remote management features. Only leave such functions active if you clearly understand them and require them.

5. Use modern Wi-Fi encryption. Choose WPA3 whenever your device supports it. If not, use the most up-to-date option available.

6. Consider a trusted VPN. It adds an extra layer of protection by encrypting your online activity.

7. Upgrade aging hardware. Older models often lack modern protections and may struggle to handle security patches or stable performance.


What users should do now

A potential restriction on any router brand is still under government review. For now, users should focus on ensuring their own devices are secured and updated. Strengthening home Wi-Fi settings, using current security practices, and replacing unsupported hardware will offer the most immediate protection while the situation continues to escalate.
