Descriptions

Mattermost fails to perform correct authorization checks when creating a playbook action, allowing users without access to the playbook to create playbook actions. If the playbook action created is to post a message in a channel based on specific keywords in a post, some playbook information, like the name, can be leaked.

Mattermost no realiza comprobaciones de autorización correctas al crear una acción del playbook, lo que permite a los usuarios sin acceso al playbook crear acciones del playbook. Si la acción del playbook creada es publicar un mensaje en un canal basado en palabras clave específicas en una publicación, se puede filtrar cierta información del playbook, como el nombre.
