Descriptions

Mattermost fails to check the Show Full Name option at the /api/v4/teams/TEAM_ID/top/team_members endpoint allowing a member to get the full name of another user even if the Show Full Name option was disabled

Mattermost no marca la opción "Show Full Name" en el endpoint /api/v4/teams/TEAM_ID/top/team_members, lo que permite a un miembro obtener el nombre completo de otro usuario incluso si la opción "Show Full Name" está deshabilitada.
