GHSA-59xc-5v89-r7pr: Duplicate Advisory: OpenClaw: Synology Chat Webhook Pre-Auth Rate-Limit Bypass Enables Brute-Force Guessing of Webhook Token
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-mf5g-6r6f-ghhm. This link is maintained to preserve external references.
Original Description
OpenClaw before 2026.3.25 contains a pre-authentication rate-limit bypass vulnerability in webhook token validation that allows attackers to brute-force weak webhook secrets. The vulnerability exists because invalid webhook tokens are rejected without throttling repeated authentication attempts, enabling attackers to guess weak tokens through rapid successive requests.
