      "value": "Movary is a self hosted web app to track and rate a user's watched movies. Prior to version 0.71.1, an ordinary authenticated user can escalate their own account to administrator by sending `isAdmin=true` to `PUT /settings/users/{userId}` for their own user ID. The endpoint is intended to let a user edit their own profile, but it updates the sensitive `isAdmin` field without any admin-only authorization check. Version 0.71.1 patches the issue."

Antes de la versión 0.71.1, un usuario autenticado ordinario puede escalar su propia cuenta a administrador enviando “isAdmin=true” a “PUT /settings/users/{userId}” para su propio ID de usuario. El endpoint está destinado a permitir que un usuario edite su propio perfil, pero actualiza el campo sensible “isAdmin” sin ninguna comprobación de autorización solo para administradores. La versión 0.71.1 corrige el problema."
