CVE-2025-1568Public exploitNetwork attack vector

Authenticated code injection via inherited Gerrit approvals

Published Apr 16, 2025 · Updated May 20, 2025

Improper access control in Google ChromeOS 16063.87.0 allows remote authenticated users to inject code through ChromiumOS Gerrit. Gerrit's project.config grants registered users addPatchSet access, while inherited copy conditions preserve prior approvals when a malicious revision is added. A registered Gerrit account can therefore replace an approved patch set before automated submission, enabling malicious code to enter builds and interrupt downstream systems.
