      "value": "dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, any authenticated API user who has their own access token can ask the collection API to evaluate permissions as a different user by supplying `user_email`. If the target user has collections, this can expose those collections through the API. In V4, once a collection id is known, the same controller also offers `add_item` and `remove_item` routes without any object-level `authorize!` checks,\ncreating a likely cross-user modification path. This is patched in version 26.06.08."

En dataCycle-CORE, el módulo que gestiona el procesamiento central y las reglas del framework, antes e incluyendo la versión 25.07.3, cualquier usuario de API autenticado que tenga su propio token de acceso puede solicitar a la API de colección que evalúe los permisos como un usuario diferente proporcionando ’user_email’. Si el usuario objetivo tiene colecciones, esto puede exponer esas colecciones a través de la API. En V4, una vez que se conoce un ID de colección, el mismo controlador también ofrece rutas ’add_item’ y ’remove_item’ sin ninguna comprobación ’authorize!’ a nivel de objeto, creando una probable ruta de modificación entre usuarios. Esto se ha parcheado en la versión 26.06.08."
