Detailsinfo

A vulnerability has been found in OpenClaw up to 2026.2.11 and classified as problematic. This vulnerability affects an unknown function of the component Hooks Endpoint. The manipulation with an unknown input leads to a timing discrepancy vulnerability. The CWE definition for the vulnerability is CWE-208.

As an impact it is known to affect confidentiality. CVE summarizes:

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.
