### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-5m9r-p9g7-679c. This link is maintained to preserve external references. ### Original Description OpenClaw before 2026.3.12 applies rate limiting only after successful webhook authentication, allowing attackers to bypass rate limits and brute-force webhook secrets. Attackers can submit repeated authentication requests with invalid secrets without triggering rate limit responses, enabling systematic secret guessing and subsequent forged webhook submission.
