{"id":"CVE-2026-31241","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.","aliases":["GHSA-gq6f-qwv9-rf4j","PYSEC-2026-2634"],"modified":"2026-07-15T01:49:02.588411184Z","published":"2026-05-12T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31241.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mem0ai/mem0","events":[{"introduced":"394203d1b5f56385d28690ea27c0d746007ff940"},{"last_affected":"394203d1b5f56385d28690ea27c0d746007ff940"}],"database_specific":{"cpe":"cpe:2.3:a:mem0:mem0:1.0.0:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.0.0"},{"last_affected":"1.0.0"}],"source":"CPE_STRING"}}],"versions":["1.0.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31241.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"}]}
