Prior to 2.57.1, a case-sensitivity flaw in the password validation logic allows any authenticated user to change their password (or an admin to change any user's password) without providing the current password. By using Title Case field name \"Password\" instead of lowercase \"password\" in the API request, the current_password verification is completely bypassed. This enables account takeover if an attacker obtains a valid JWT token through XSS, session hijacking, or other means. This vulnerability is fixed in 2.57.1."}, {"lang": "es", "value": "File Browser proporciona una interfaz de gesti\u00f3n de archivos dentro de un directorio especificado y puede ser utilizado para subir, eliminar, previsualizar, renombrar y editar archivos. Anterior a la 2.57.1, una falla de sensibilidad a may\u00fasculas y min\u00fasculas en la l\u00f3gica de validaci\u00f3n de contrase\u00f1as permite a cualquier usuario autenticado cambiar su contrase\u00f1a (o a un administrador cambiar la contrase\u00f1a de cualquier usuario) sin proporcionar la contrase\u00f1a actual. Al usar el nombre de campo en formato 'Title Case' 'Password' en lugar de 'password' en min\u00fasculas en la solicitud de la API, la verificaci\u00f3n de current_password es completamente eludida. Esto permite la toma de control de cuenta si un atacante obtiene un token JWT v\u00e1lido a trav\u00e9s de XSS, secuestro de sesi\u00f3n, u otros medios.
