HIGH7.5EPSS 0.05%mem0 server lacks authentication and authorization controls for its memory management API endpoints
Published: 5/12/2026Modified: 5/28/2026
Description
The mem0 1.0.0 server lacks authentication and authorization controls for its memory management API endpoints. Critical functions such as updating memory records (PUT /memories/{memory_id}) are exposed without any verification of the requester's identity or permissions. A remote attacker can exploit this by sending unauthenticated requests to modify, overwrite, or delete arbitrary memory records, leading to unauthorized data manipulation and potential data loss.
