Summary
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.

"value": "Versiones de OpenClaw anteriores a 2026.3.2 contienen una vulnerabilidad de denegaci\u00f3n de servicio en los manejadores de webhooks para BlueBubbles y Google Chat que analizan los cuerpos de las solicitudes antes de realizar la autenticaci\u00f3n y la validaci\u00f3n de firma. Atacantes no autenticados pueden explotar esto enviando cuerpos de solicitud lentos o sobredimensionados para agotar los recursos del analizador y degradar la disponibilidad del servicio."
