Critical React Native CLI Vulnerability Enables OS Command Injection  

Summary: React Native is an open source framework maintained by Meta . A critical remote code execution vulnerability in the @react-native-community/cli package, a core toolset used by React Native developers. The flaw allows unauthenticated remote attackers to execute arbitrary OS commands on machines running the React Native Metro development server.

Severity  Critical 
CVSS Score  9.8 
CVEs  CVE-2025-11953 
POC Available  Yes 
Actively Exploited  No 
Advisory Version  1.0 

Overview 

A critical remote code execution vulnerability in the @react-native-community/cli package, a core toolset used by React Native developers. The flaw allows unauthenticated remote attackers to execute arbitrary OS commands on machines running the React Native Metro development server.

The vulnerability comes from unsafe input handling in the /open-url endpoint using the insecure open() function, and a React Native CLI flaw that exposes the server to remote code execution. Immediate updates and mitigations are recommended for all using the affected package versions. 

Vulnerability Name  CVE ID  Product Affected  Severity  Affected Version 
 OS Command Injection  CVE-2025-11953  @react-native-community/cli @react-native-community/cli-server-api  Critical  @react-native-community/cli-server-api versions 4.8.0 through 20.0.0-alpha.2 

Technical Summary 

The Metro development server’s /open-url HTTP POST endpoint unsafely passes unsanitized user input (url field) as an argument to the open() function from the open NPM package which leads to OS command injection.

On Windows, the vulnerability allows arbitrary shell command execution with full control over parameters via cmd /c start command invocation. On macOS/Linux, arbitrary executables can be launched with limited parameter control. Further exploitation may lead to full RCE, but not confirmed yet. The server binds to all interfaces by default (0.0.0.0), exposing the endpoint externally to unauthenticated network attackers. 

CVE ID  Component Affected  Vulnerability Details  Impact 
CVE-2025-11953  Development Server’s /open-url Endpoint  The React Native CLI’s Metro server binds to external interfaces by default and exposes a command injection flaw, letting remote attackers send POST requests to run arbitrary executables or shell commands on Windows.  Remote OS Command Injection 

Recommendations 

  • Update to @react-native-community/cli-server-api version 20.0.0 or later immediately. 

If upgrading is not possible, 

  • Restrict the Metro server to localhost by adding the flag: –host 127.0.0.1 when starting the server. 
  • Integrate static and dynamic code analysis tools in development pipelines to detect injection risks early. 

How these kind of security flaw can cause damage?

This vulnerability poses a critical threat to React Native developers using the Metro development server due to unauthenticated RCE via network exposure. For any unauthenticated network attacker this is privilege they can weaponize the flaw and send a specially crafted POST request to the server. Then run arbitrary commands.

The attack takes a different turn when it comes to Windows and the exploitation is severe. The attackers can also execute arbitrary shell commands with fully controlled arguments, while on Linux and macOS, it can be widely used to execute arbitrary binaries with limited parameter control.

The vulnerable endpoint, /open-stack-frame, is designed to help developers open a file in their editor at a specific line number when debugging errors. This endpoint accepts POST requests with parameters such as file and lineNumber.

The incident highlight requirement for more rigorous input validation and secure-by-default configurations in developer environments.

What should organizations looks for while selecting a comprehensive tools that can provide thorough combing across their IT environment, networks, applications and cloud infrastructure.

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.

High-severity path traversal vulnerability was identified in Docker Compose

Docker Compose Path Traversal Vulnerability Enables Arbitrary File Write and System Compromise  

Summary: 

OEM Docker  
Severity High 
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.
