Technical description

The mem0 1.0.0 server lacks authentication and authorization controls for its memory reset and table re-creation functionality accessible via the DELETE /memories endpoint.

This can cause unexpected table re-creation, schema disruption, potential data loss, and denial of service for the memory management service.
