CVE-2026-76037

Sandbox escape via crashpad link following

Published Aug 18, 2026 · Updated Aug 20, 2026

Link following in CredentialProvider in Google Chrome before 151.0.7922.169 on Windows allows local attackers to execute code outside the sandbox. The GCPW crash-reporting code used a Crashpad database path under the SYSTEM TEMP directory and followed attacker-controlled links there instead of restricting writes to the properly ACLed ProgramData-based data directory. Reachability requires local code execution on the host, but a successful exploit can redirect privileged crash-dump writes and turn that file-operation flaw into code execution beyond Chrome's sandbox.
