OpenClaw < 2026.2.12 - Timing Attack in Hooks Token Authentication

Published Mar 5, 2026 CVSS 4.0 · 8.2 High EPSS < 1% KEV · Not listed
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.
