MEDIUM

OpenClaw < 2026.3.12 - Webhook Rate Limiting Bypass via Pre-Authentication Secret Validation

Title source: cna

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.
