Executive Summary

This vulnerability exists in OpenClaw versions prior to 2026.3.2 and involves a denial of service issue in webhook handlers for BlueBubbles and Google Chat.

The problem arises because these webhook handlers parse request bodies before performing authentication and signature validation.

As a result, unauthenticated attackers can exploit this by sending slow or oversized request bodies, which exhaust parser resources and degrade the availability of the service.

Impact Analysis

This vulnerability can impact you by causing a denial of service condition in the affected OpenClaw webhook handlers.

Attackers can send specially crafted requests that consume excessive parsing resources, leading to degraded service availability or complete service outages.

Since the vulnerability allows unauthenticated attackers to exploit it, it poses a risk of service disruption without requiring any prior access.
