Descriptions

Mattermost versions 9.5.x <= 9.5.3, 9.7.x <= 9.7.1 and 8.1.x <= 8.1.12 fail to perform a proper authorization check in the /api/v4/groups/<group-id>/channels/<channel-id>/link endpoint which allows a user to learn the members of an AD/LDAP group that is linked to a team by adding the group to a channel, even if the user has no access to the team.

Las versiones 9.5.x <= 9.5.3, 9.7.x <= 9.7.1 y 8.1.x <= 8.1.12 de Mattermost no realizan una verificación de autorización adecuada en /api/v4/groups// canales//link endpoint que permite a un usuario conocer los miembros de un grupo AD/LDAP que está vinculado a un equipo agregando el grupo a un canal, incluso si el usuario no tiene acceso al equipo.
