OpenClaw < 2026.2.13 - Timing Attack via Hook Token Comparison

Published Mar 5, 2026 · Updated Mar 9, 2026 · Assigned by VulnCheck

Description

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.
