Descriptions

Mattermost fails to properly validate requests to the Calls plugin, allowing an attacker sending a request without a User Agent header to cause a panic and crash the Calls plugin

Mattermost no valida correctamente las solicitudes al complemento Calls, lo que permite que un atacante que envíe una solicitud sin un encabezado de Agente de Usuario cause pánico y bloquee el complemento Calls.
