Descriptions

Mattermost fails to handle a null request body in the /add endpoint, allowing a simple member to send a request with null request body to that endpoint and make it crash. After a few repetitions, the plugin is disabled.

Mattermost no logra manejar un cuerpo de solicitud nulo en el endpoint /add, lo que permite que un miembro simple envíe una solicitud con un cuerpo de solicitud nulo a ese endpoint y haga que falle. Después de algunas repeticiones, el complemento se desactiva.
