{"id":"CVE-2026-31243","details":"The mem0 1.0.0 server lacks authentication and authorization controls for its memory reset and table re-creation functionality accessible via the DELETE /memories endpoint. An unauthenticated attacker can send a DELETE request that triggers a reset operation, leading to the execution of a CREATE TABLE SQL statement. This can cause unexpected table re-creation, schema disruption, potential data loss, and denial of service for the memory management service.","modified":"2026-08-12T03:51:13.488817073Z","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-2026-31243.json"},"references":[{"type":"WEB","url":"https://www.notion.so/CVE-2026-31243-35d1e139318881c6a6cffbe366c238a6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31243.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31243"},{"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":{"source":"CPE_STRING","cpe":"cpe:2.3:a:mem0:mem0:1.0.0:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.0.0"},{"last_affected":"1.0.0"}]}}],"versions":["1.0.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31243.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"}]}
