Title

OpenClaw < 2026.2.12 - Timing Attack in Hooks Token Authentication

Summary

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.

Severity ?
