OpenClaw OpenClaw
OpenClaw < 2026.2.12 - Timing Attack in Hooks Token Authentication
CVSS 4.0
8.2High
Official description
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.
