Summary
OpenClaw < 2026.3.25 - Denial of Service via Unauthenticated Webhook Request Parsing
Details

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.
