Mozilla has addressed a critical security vulnerability, CVE-2025-2857, in its Firefox browser for Windows. This flaw, discovered in Firefox’s inter-process communication (IPC) code, allowed a compromised child process to cause the parent process to return an unintended powerful handle, leading to a sandbox escape. The issue was identified after Google’s recent patch of a similar Chrome vulnerability, CVE-2025-2783, exploited by state-sponsored attackers.
To mitigate this vulnerability, Mozilla released updates for Firefox version 136.0.4, Firefox Extended Support Release (ESR) versions 128.8.1, and 115.21.1 for Windows users. Given the potential severity of sandbox escape exploits, users are strongly encouraged to update their browsers promptly to protect against possible attacks.
The Tor Project, which builds its browser on a modified version of Firefox ESR, also released an emergency security update, version 14.0.8, for Windows users. Tor Browser users should update immediately to ensure their security and maintain anonymity online.
This discovery underscores the importance of continuous vigilance in software development and the necessity for developers to proactively assess their codebases, especially when similar platforms encounter security issues. Regular updates and prompt patching are vital in maintaining the security and integrity of software applications.
Users are advised to enable automatic updates and stay informed about the latest security advisories from their software providers. Maintaining up-to-date software is a fundamental step in protecting against emerging threats and ensuring a secure computing environment.
