{"id":"PYSEC-2026-2634","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.","aliases":["CVE-2026-31241","GHSA-gq6f-qwv9-rf4j"],"modified":"2026-07-13T16:32:14.657379485Z","published":"2026-07-13T15:15:46.461897Z","references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31241"},{"type":"PACKAGE","url":"https://github.com/mem0ai/mem0"},{"type":"WEB","url":"https://www.notion.so/CVE-2026-31241-35d1e139318881459ae5e6f0d7dc6f0f"},{"type":"PACKAGE","url":"https://pypi.org/project/mem0ai"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-gq6f-qwv9-rf4j"}],"affected":[{"package":{"name":"mem0ai","ecosystem":"PyPI","purl":"pkg:pypi/mem0ai"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.0.0"}]}],"versions":["0.0.1","0.0.10","0.0.11","0.0.12","0.0.13","0.0.14","0.0.15","0.0.16","0.0.17","0.0.18","0.0.19","0.0.2","0.0.20","0.0.20rc1","0.0.21","0.0.3","0.0.4","0.0.5","0.0.6","0.0.7","0.0.8","0.0.9","0.1.0","0.1.1","0.1.10","0.1.100","0.1.101","0.1.102","0.1.103","0.1.104","0.1.106","0.1.107","0.1.107rc1","0.1.107rc2","0.1.108","0.1.109","0.1.11","0.1.110","0.1.111","0.1.112","0.1.113","0.1.114","0.1.115","0.1.116","0.1.117","0.1.118","0.1.12","0.1.13","0.1.14","0.1.15","0.1.16","0.1.17","0.1.18","0.1.19","0.1.2","0.1.20","0.1.20a0","0.1.21","0.1.22","0.1.23","0.1.24","0.1.25","0.1.26","0.1.27","0.1.28","0.1.29","0.1.3","0.1.30","0.1.31","0.1.32","0.1.33","0.1.34","0.1.35","0.1.36","0.1.37","0.1.38","0.1.39","0.1.4","0.1.40","0.1.41","0.1.42","0.1.43","0.1.44","0.1.45","0.1.45rc1","0.1.46","0.1.47","0.1.48","0.1.49","0.1.5","0.1.50","0.1.52","0.1.53","0.1.54","0.1.55","0.1.56","0.1.57","0.1.58","0.1.59","0.1.6","0.1.60","0.1.61","0.1.62","0.1.63","0.1.65","0.1.66","0.1.67","0.1.69","0.1.7","0.1.70","0.1.71","0.1.72","0.1.73","0.1.74","0.1.75","0.1.76","0.1.77","0.1.78","0.1.78a0","0.1.78a1","0.1.78a2","0.1.79","0.1.8","0.1.80","0.1.81","0.1.81a0","0.1.81a1","0.1.81a2","0.1.82","0.1.83","0.1.84","0.1.84a1","0.1.85","0.1.86","0.1.87","0.1.88","0.1.89","0.1.9","0.1.90","0.1.91","0.1.92","0.1.93","0.1.94","0.1.95","0.1.96","0.1.96rc1","0.1.97","0.1.98","0.1.99","0.1.99a0","0.1.99a1","0.1.99a2","0.1.99a3","1.0.0","1.0.0b0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/mem0ai/PYSEC-2026-2634.yaml"}}],"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"}]}
