CVE-2026-31240 (GCVE-0-2026-31240)

Vulnerability from cvelistv5 – Published: 2026-05-12 00:00 – Updated: 2026-05-14 19:54
VLAI
Summary
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
