Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-rm59-992w-x2mv. This link is maintained to preserve external references.

OpenClaw before 2026.3.22 contains an unauthenticated resource exhaustion vulnerability in voice call webhook handling that buffers request bodies before provider signature checks. Attackers can send large or malicious webhook requests to exhaust server resources without authentication by bypassing signature validation.
