Lifecycle Timeline
3Description
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.
Analysis
OpenClaw versions before 2026.2.12 are vulnerable to timing-based token extraction attacks due to non-constant-time string comparison in hook authentication. A network-based attacker can exploit this side-channel vulnerability to gradually recover the hook validation token through repeated timing measurements across multiple requests. …
