Summary Duplicate Advisory: OpenClaw has Bypass in Webhook Rate Limiting via Pre-Authentication Secret Validation ### Duplicate Advisory This advisory has been withdrawn because CVE-2026-34508 has been rejected as a duplicate of CVE-2026-34505. This link is maintained to preserve external references. ### Original Description OpenClaw before 2026.3.12 applies rate limiting only after webhook authentication succeeds, allowing attackers to bypass rate limits and brute-force webhook secrets without triggering 429 responses. Attackers can repeatedly guess invalid secrets to discover valid credentials and subsequently submit forged Zalo webhook traffic.
