NVD description
OpenClaw versions prior to 2026.3.2 contain a denial of service vulnerability in webhook handlers for BlueBubbles and Google Chat that parse request bodies before performing authentication and signature validation. Unauthenticated attackers can exploit this by sending slow or oversized request bodies to exhaust parser resources and degrade service availability.
What to do
- Upgrade OpenClaw to
2026.3.2or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
