PYSEC-2026-2635

Vulnerability from pysec - Published: 2026-07-13 15:15 - Updated: 2026-07-13 16:04

Details

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.

Severity

7.5 (High)
