  3. CVE-2025-3518
It technically possible for a user to upload a file to a conversation despite the file upload functionality being disabled. The file upload functionality can be enabled or disabled for specific use cases through configuration. In case the functionality is disabled for at least one use case, the system nevertheless allows files to be uploaded through direct API requests. During the upload file, interception and allowed file type rules are still applied correctly. If file sharing is generally enabled, this issue is not of concern.

Summary
  • (es) Es técnicamente posible que un usuario suba un archivo a una conversación a pesar de que la función de subida de archivos esté deshabilitada. Esta función se puede habilitar o deshabilitar para casos de uso específicos mediante la configuración. Si la función está deshabilitada para al menos un caso de uso, el sistema permite la subida de archivos mediante solicitudes directas a la API. Durante la subida, las reglas de interceptación y de tipos de archivo permitidos se aplican correctamente. Si el uso compartido de archivos está habilitado en general, este problema no es preocupante.
