Summary
Duplicate Advisory: OpenClaw: Feishu webhook reads and parses unauthenticated request bodies before signature validation
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-3h52-cx59-c456. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.3.25 parses JSON request bodies before validating webhook signatures, allowing unauthenticated attackers to force resource-intensive parsing operations. Remote attackers can send malicious webhook requests to trigger denial of service by exhausting server resources through forced JSON parsing before signature rejection.
