AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-07-30T19:17:02.100Z and has not been modified since then. The NVD entry is currently Undergoing Analysis. IBM Langflow OSS 1.0.0 through 1.8.4 contains multiple broken access control vulnerabilities in its file handling API. 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, allowing authenticated users to 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. Users of IBM Langflow OSS, especially those with multi-user deployments, should be aware of this vulnerability and take defensive actions to prevent unauthorized access to sensitive data. Medium-priority defensive actions are recommended due to the potential for unauthorized disclosure of sensitive data in multi-user deployments of IBM Langflow OSS. Evidence from the NVD and IBM support pages indicates that IBM Langflow OSS contains broken access control vulnerabilities in its file handling API. The /api/v1/files/images/{flow_id}/{file_name} endpoint lacks authentication and authorization checks, while the /api/v1/files/download/{flow_id}/{file_name} endpoint fails to validate resource ownership properly.
