Lifecycle Timeline
3Description
OpenClaw versions prior to 2026.2.13 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 recover the authentication token.
Analysis
OpenClaw versions before 2026.2.13 are vulnerable to timing side-channel attacks on hook token validation due to use of non-constant-time string comparison. Remote attackers can exploit this weakness by measuring response times across multiple requests to gradually recover authentication tokens for the hooks endpoint. …
