mem0 server lacks authentication and authorization controls for its memory creation API endpoint

Medium5.3CVE-2026-31245 · Published May 12, 2026 · updated Jul 13, 2026

The mem0 1.0.0 server lacks authentication and authorization controls for its memory creation API endpoint (POST /memories). The endpoint allows unauthenticated users to submit arbitrary memory records without verifying their identity or permissions. A remote attacker can exploit this by sending unauthenticated POST requests to create malicious or spoofed memory entries in the database, leading to unauthorized data injection and potential data pollution.
