Descriptions

Mattermost Playbooks plugin v1.24.0 and earlier fails to properly check the limit on the number of webhooks, which allows authenticated and authorized users to create a specifically drafted Playbook which could trigger a large amount of webhook requests leading to Denial of Service.

El plugin Mattermost Playbooks versiones v1.24.0 y anteriores, no comprueba correctamente el límite del número de webhooks, lo que permite a usuarios autenticados y autorizados crear un Playbook específicamente redactado que podría desencadenar una gran cantidad de peticiones de webhooks conllevando a una Denegación de Servicio
