CVE-2026-31244 — Unauthenticated single memory record delete via mem0 DELETE /memories/{memory_id}

MITRE service request: 1988584

Status: RESERVED (pending a qualifying public reference per CNA Rules §5.3).

Official CVE description

The mem0 1.0.0 server lacks authentication and authorization controls for its memory deletion API endpoint (DELETE /memories/{memory_id}). The endpoint allows unauthenticated users to delete arbitrary memory records without verifying their identity or permissions. A remote attacker can exploit this by sending unauthenticated DELETE requests to remove any memory entry from the database, leading to unauthorized data loss and potential denial of service.

Summary

Knowing (or guessing) opaque memory_id tokens is enough to delete arbitrary rows—no bearer token, no row ownership check before Memory.delete() issues SQL DELETE.
