Critical Brash Vulnerability: Blink Engine Flaw Breaks Chromium Browsers 

Overview : Brash Vulnerability works on Google Chrome and all web browsers that run on Chromium.

A newly disclosed vulnerability, Brash, exposed a critical architectural flaw in Chromium’s Blink rendering engine. Blink is Chromium’s open-source rendering engine responsible for parsing HTML, CSS, and JavaScript, building the DOM and render trees, and executing script-driven updates to the browser interface.

It underpins the user experience of all Chromium-based browsers and is a core component of their performance and stability.

The issue allows a malicious web page to crash Chromium-based browsers within seconds, including Chrome, Microsoft Edge, Brave, Opera etc. The attack works by overloading Blink’s main UI thread using a flood of unthrottled DOM operations. A public proof-of-concept (PoC) exploit is available and can be tested on machines, that escalating the urgency for patching across all Chromium-based platforms.  

Technical Details  

Blink lacks any rate limiting or coalescing on rapid document. title updates, allowing an attacker to flood the browser with millions of DOM mutations per second.  

This saturates the browser’s main UI thread, causing extreme CPU usage and blocking event processing, which leads to the browser tab freezing or crashing within 15 to 60 seconds. The exploit can also be use to trigger after a delay or at a precise scheduled time, turning it into a highly controllable logic bomb.  

The exploit requires no special permissions beyond navigating to a malicious page, presenting a severe and immediate operational risk until patches are deployed. 

Attack Flow 

Recommendations 

You can follow the recommendations below 

  • Avoid clicking on suspicious or untrusted links, especially those prompting unexpected redirects or downloads. 
  • Keep all Chromium-based browsers (Chrome, Edge, Brave etc.) updated with the latest security patches as vendors release fixes. 
  • Enforce automatic browser updates within organizations to ensure all users receive critical patches promptly. 
  • Monitor computer endpoints for unusual CPU spikes related to browser processes, which can indicate ongoing exploitation attempts. 
  • Educate users and employees about the risk of drive-by attacks through malicious websites and the importance of security awareness. 

Conclusion: 
The Brash vulnerability reveals how a simple architectural oversight. It lets attackers crash browsers by flooding them with too many title updates too fast, causing the browser to freeze or crash. This attack can be scheduled to happen later, making it harder to detect.

Mozilla Firefox and Apple Safari are immune to the attack, as are all third-party browsers on iOS, given that they are all based on WebKit.

The best defense is to keep browsers updated, avoid suspicious links and stay alert for unusual computer slowdowns.

CVSS Score 8.9 
CVEs CVE-2025-62725 
Date of Announcement 2025-10-28 
Actively Exploited No 
Exploited in Wild No 
Advisory Version 1.0 

Overview 

A high-severity path traversal vulnerability was identified in Docker Compose, a widely-used tool for defining and managing multi-container Docker applications.

This flaw occurs in the handling of remote OCI-based Compose artifacts, allowing an attacker to craft malicious artifact annotations that bypass directory restrictions. As a result, malicious files can be written outside the intended cache directory on the host system.

This vulnerability can be triggered even by seemingly harmless commands such as docker compose ps or docker compose config that resolve remote artifacts. Organizations should upgrade immediately to avoid possible system compromise. 

Vulnerability Name CVE ID Product Affected Severity CVSS Score 
Path Traversal in OCI Artifacts Allowing Arbitrary File Write CVE-2025-62725 Docker Compose CLI High 8.9 

Technical Summary 

Docker Compose added support for fetching Compose files as OCI artifacts from remote registries. These artifacts contain layers with annotations indicating file paths for writing.

The vulnerability exists because Docker Compose did not sanitize or validate these path annotations prior to writing files, allowing path traversal sequences to escape the cache directory.

Attackers can exploit this by publishing malicious OCI artifacts with crafted annotations, leading to arbitrary file writes anywhere the Compose process has permissions, potentially overwriting sensitive files such as SSH authorized_keys, escalating privileges and compromising the host. The flaw affects Docker Compose versions prior to v2.40.2. 

CVE ID System Affected  Vulnerability Details Impact 
 CVE-2025-62725   Docker Compose (Linux, Windows, macOS) Path traversal via malicious remote OCI artifact annotations allowing arbitrary file write outside the Compose cache directory. 
 		Arbitrary file write, potential system compromise, privilege escalation. 

Remediation 

Apply security patches immediately to mitigate risks from privilege escalation and container escape. 

  • Update Docker-compose to v2.40.2 or the latest one. 

Conclusion 

Docker Compose vulnerability poses a serious risk of arbitrary file writes and system compromise through malicious OCI artifacts.

Due to the ease of exploitation when using remote Compose files, all users and organizations should upgrade to the patched Docker Compose version immediately, scrutinize remote artifact usage, and enhance their container security hygiene to mitigate this significant threat.

Copilot Studio SupplyChain Attack Steals OAuth Tokens via CoPhishing

Summary 

The CoPhish attack is a sophisticated phishing technique exploiting Microsoft Copilot Studio to steal OAuth tokens by tricking users into granting attackers unauthorized access to their Microsoft Entra ID accounts.

By Copilot Studio’s customizable AI agents, attackers create chatbots hosted on legitimate Microsoft domains that wrap traditional OAuth consent attacks in an authentic-looking interface, increasing the likelihood of successful deception. 

Technical Details 

The attackers often use a trial license or compromised tenant to create the agent, backdooring the authentication workflow so that, post-consent, OAuth tokens are exfiltrated via HTTP to attacker infrastructure.

Few Demo links like copilotstudio.microsoft.com add credibility, closely mimicking official Microsoft Copilot services, and victims see familiar branding and login flows.

While Microsoft has implemented consent policy updates including blocking risky permissions by default for most users significant gaps remain: unprivileged users can still approve internal apps and privileged admins retain broad consent authority.

Tokens exfiltrated by CoPhish can be used for impersonation, data theft or sending further phishing emails, often going undetected as the traffic is routed through Microsoft infrastructure. 

malicious CopilotStudio page                                                                                                                         Source: securitylabs.datadoghq.com 

Attack Flow 

Step Description 
1. Build Malicious Copilot Agent Attackers create a customized Copilot Studio chatbot, usually on a trial license within their own or a compromised Microsoft tenant, configuring it to appear as a legitimate assistant. 
2. Backdoor Authentication Workflow The agent’s “Login” topic is modified to include an HTTP request that will exfiltrate any OAuth tokens granted by users during authentication. 
3. Share Demo Link Attackers generate and distribute demo website URL (like, copilotstudio.microsoft.com) pointing to the malicious chatbot, mimicking official Copilot Studio services and passing basic domain trust checks. 
4. Victim and Trigger Consent Victims access the link, interact with the familiar interface, and are prompted to login, beginning an OAuth consent flow that requests broad Microsoft Graph permissions. 
5. Token Exfiltration After the victim consents, the agent collects the issued OAuth token and sends it via HTTP to an attacker-controlled server, often relaying through Microsoft IP addresses to avoid detection in standard traffic logs. 
6. Abuse Granted Permissions Attackers use the stolen token to impersonate the victim, accessing emails, calendars, and files or conducting further malicious actions such as sending phishing emails or stealing sensitive data. 
7. Persist and Retarget Due to policy gaps, attackers can repeat the process targeting both internal and privileged users, tailoring requested app permissions and adapting to Microsoft’s evolving security measures. 

                             Source: securitylabs.datadoghq.com 

Why It’s Effective 

  • Leverages trusted Microsoft domains and branding with realistic AI chatbot flows, bypassing phishing detection and user suspicion. 
  • Bypasses multi-factor authentication by stealing fully privileged OAuth tokens that persist until revoked. 
  • Targets both regular users and privileged admins by adapting requested permissions, making it scalable and versatile. 

Recommendations 

Here are some recommendations below 

  • Enforce strict Microsoft Entra ID consent policies to limit user approval of app permissions, especially high-risk scopes. 
  • Restrict or disable user creation and publishing of Copilot Studio agents unless explicitly authorized by admins. 
  • Monitor Entra ID audit logs and Microsoft Purview for suspicious app consent, agent creation or modifications in Copilot workflows. 
  • Apply Azure AD Conditional Access requiring MFA and device compliance for accessing Copilot Studio and related AI services. 
  • Implement tenant-level Data Loss Prevention (DLP) and sensitivity labeling 
  • Educate users on phishing risks and regularly reviewing/revoking app permissions and tokens. 

Conclusion: 
CoPhish highlights how AI-powered low-code platforms like Microsoft Copilot Studio can be exploited for advanced phishing attacks targeting identity systems.

Despite Microsoft’s improvements to consent policies, significant risks remain, requiring organizations to enforce strict consent controls, limit app creation, and monitor Entra ID logs vigilantly. As AI-driven tools grow, proactive security measures are essential to defend against these evolving hybrid threats leveraging trusted cloud services.

Spring Framework Annotation Detection Vulnerability CVE-2025-41249 Spring Framework Medium 6.2.11 (Open Source) 6.1.23 (Commercial Support) 5.3.45 (Commercial Support)  

Technical Summary 

The vulnerability arises when Spring applications use inheritance (where a class inherits methods from another class) and generics (a way to define methods or classes that can handle different types of data) together. If a secured method, like one marked with the @PreAuthorize annotation (used to enforce security checks), is declared in a generic superclass or interface without clear type definitions, Spring might fail to recognize the security annotation at runtime. This means unauthorized users could potentially access these methods. This issue affects Spring Security versions 6.4.0 to 6.5.3 and Spring Framework versions 5.3.0 to 6.2.10. The Spring team has since released updates to better handle security annotations in such cases, ensuring proper authorization checks. 

CVE ID System Affected  Vulnerability Details Impact 
CVE-2025-41248 Spring Security 6.4.0 – 6.4.9 6.5.0 – 6.5.3 Spring Security may fail to detect method-level security annotations applied to generic superclasses or interfaces, resulting in unauthorized access. Unauthorized access  
CVE-2025-41249 Spring Framework 6.2.0 – 6.2.10 6.1.0 – 6.1.22 5.3.0 – 5.3.44 Older, unsupported versions are also affected.  Spring Framework does not consistently recognize security annotations on methods declared in generic superclasses or interfaces, which can lead to authorization bypass. Authorization bypass. 

Remediation: 

Users should immediately update to the latest patched versions of Spring Security and Spring Framework: 

Spring Security 
Affected Version Fix Version 
6.5.x 6.5.4 
6.4.x 6.4.10 
Spring Framework 
Affected Version Fix Version 
6.2.x 6.2.11 
6.1.x 6.1.23 
6.0.x N/A (OOS) 
5.3.x 5.3.45 

Conclusion: 
These vulnerabilities cause Spring Security and Spring Framework to sometimes miss detecting method-level security annotations in generic type hierarchies. This can allow unauthorized users to bypass authorization checks, exposing protected functionality. While the severity is medium, it is important to update to the fixed versions promptly and review security annotation usage on generics to maintain proper access control.
