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.","published":"2026-05-12T00:00:00.000Z","modified":"2026-05-14T19:54:13.934Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":{"score":0.00372,"percentile":0.2996,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/mem0ai/mem0"},{"type":"WEB","url":"https://www.notion.so/CVE-2026-31240-35d1e13931888170964ae035c04a8f18"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-05-14T19:54:13.934Z"}}
