GHSA-cxfr-3qp8-hpmw: Duplicate Advisory: OpenClaw: Zalo webhook rate limiting could be bypassed before secret validation

March 31, 2026 (updated April 6, 2026)

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This advisory has been withdrawn because it is a duplicate of GHSA-5m9r-p9g7-679c.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.
