Name of the Vulnerable Software and Affected Versions mem0 version 1.0.0

Description The server lacks authentication and authorization controls for the memory deletion API endpoint "DELETE /memories/{memory id}". This allows unauthenticated users to delete arbitrary memory records without identity or permission verification. A remote attacker can send unauthenticated requests to remove any memory entry from the database, resulting in unauthorized data loss and potential denial of service.

Recommendations Update mem0 version 1.0.0 to a version that implements proper authentication and authorization for the "DELETE /memories/{memory id}" endpoint. As a temporary workaround, restrict access to the "DELETE /memories/{memory id}" API endpoint to minimize the risk of exploitation.
