Google Chrome Zero-Day Vulnerability CVE-2025-2783

Identified in March 2025, CVE-2025-2783 is a high-severity vulnerability in Google Chrome's Mojo inter-process communication (IPC) framework on Windows systems. This vulnerability allows attackers to bypass Chrome's sandbox protections and execute arbitrary code on victim machines. The flaw was exploited in a targeted cyber-espionage campaign named "Operation ForumTroll," which targeted Russian media and government institutions. Google responded to this vulnerability by releasing a security update (version 134.0.6998.177/.178) on March 25, 2025. Users are strongly advised to update their browsers to protect against potential exploits.

Technical Details of CVE-2025-2783

The vulnerability arises from a logical error between Chrome's sandbox mechanism and the Windows operating system kernel. This error enables attackers to bypass the browser's sandbox isolation, which is designed to limit the impact of exploits. The flaw is particularly critical as it allows unauthorized execution of code within the Windows environment. CISA has added CVE-2025-2783 to its Known Exploited Vulnerabilities Catalog, urging organizations to patch the flaw before April 17, 2025.
