      "value": "IBM Langflow OSS 1.0.0 through 1.8.4 contains multiple broken access control vulnerabilities in its file handling API that allow unauthorized access to user files.The /api/v1/files/images/{flow_id}/{file_name} endpoint does not enforce authentication or authorization checks, allowing unauthenticated remote attackers to retrieve image files associated with any flow by specifying a valid flow_id and file_name.Additionally, the /api/v1/files/download/{flow_id}/{file_name} endpoint requires authentication but fails to properly validate ownership of the requested resource. As a result, an authenticated user can access files belonging to other users by supplying arbitrary identifiers, leading to an authorization bypass (IDOR).Successful exploitation may result in unauthorized disclosure of sensitive data, including files stored in private flows. This issue breaks tenant isolation in multi-user deployments."

      "value": "IBM Langflow OSS 1.0.0 hasta 1.8.4 contiene múltiples vulnerabilidades de control de acceso roto en su API de manejo de archivos que permiten el acceso no autorizado a archivos de usuario. El endpoint /api/v1/files/images/{flow_id}/{file_name} no aplica comprobaciones de autenticación o autorización, permitiendo a atacantes remotos no autenticados recuperar archivos de imagen asociados con cualquier flujo al especificar un flow_id y file_name válidos. Además, el endpoint /api/v1/files/download/{flow_id}/{file_name} requiere autenticación pero no valida correctamente la propiedad del recurso solicitado. Como resultado, un usuario autenticado puede acceder a archivos pertenecientes a otros usuarios al proporcionar identificadores arbitrarios, lo que lleva a una omisión de autorización (IDOR). La explotación exitosa puede resultar en la divulgación no autorizada de datos sensibles, incluyendo archivos almacenados en flujos privados. Este problema rompe el aislamiento de inquilinos en despliegues multiusuario."
