High (8.2) in openclaw openclaw. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in openclaw 2026.2.12.
OpenClaw versions prior to 2026.2.12 use non-constant-time string comparison for hook token validation, allowing attackers to infer tokens through timing measurements. Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually determine the authentication token.
