{"id":"CVE-2026-31241","aliases":["GHSA-gq6f-qwv9-rf4j","PYSEC-2026-2634"],"url":"https://o3.security/vulnerability/CVE-2026-31241","summary":"mem0 server lacks authentication and authorization controls for its memory deletion API endpoint","details":"The mem0 1.0.0 server lacks authentication and authorization controls for its memory deletion API endpoint (DELETE /memories). The endpoint allows unauthenticated users to delete memory records by specifying arbitrary user identifiers (e.g., user_id, run_id, agent_id) in the request query parameters. A remote attacker can exploit this by sending unauthenticated DELETE requests to erase memory data for any user, leading to unauthorized data loss and denial of service.","published":"2026-05-12T00:00:00Z","modified":"2026-08-07T11:31:25.919456579Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"},"epss":{"score":0.00386,"percentile":0.31387,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"mem0ai","fixedVersion":null}],"fix":null,"references":[{"type":"WEB","url":"https://www.notion.so/CVE-2026-31241-35d1e139318881459ae5e6f0d7dc6f0f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31241.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31241"},{"type":"PACKAGE","url":"https://github.com/mem0ai/mem0"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:25.919456579Z"}}
