CVE-2025-2783 is a vulnerability in Google Chrome specifically affecting Windows users. It is described as an "incorrect handle provided in unspecified circumstances in Mojo on Windows." Mojo is a collection of runtime libraries that facilitates inter-process communication (IPC). This vulnerability allowed attackers to bypass Chrome's sandbox protection. The vulnerability was exploited in the wild as part of a targeted attack dubbed "Operation ForumTroll," which targeted media outlets, educational institutions, and government organizations in Russia. The attack involved phishing emails with malicious links that, when clicked in Chrome, led to immediate infection. The exploit was designed to work with another exploit that enabled remote code execution, although the second exploit was not obtained by researchers. Google has addressed this vulnerability in Chrome version 134.0.6998.177/.178 for Windows.

Description: Incorrect handle provided in unspecified circumstances in Mojo in Google Chrome on Windows prior to 134.0.6998.177 allowed a remote attacker to perform a sandbox escape via a malicious file. (Chromium security severity: High)
