A user with the Technician profile can clone a Super-Admin account with a new login and password, since User::getCloneRelations() copies every Profile_User and Group_User assignment without permission checks, yielding an attacker-controlled Super-Admin account.","published":"2026-11-03T15:17:15.660Z","modified":"2026-11-04T10:30:55.360870970Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/glpi-project/glpi/commit/10a827c8c1868a0a65ab977d30878ff16547d9a7","label":"glpi-project/glpi@10a827c"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/121xxx/CVE-2026-121559.json"},{"type":"PACKAGE","url":"https://github.com/glpi-project/glpi"},{"type":"FIX","url":"https://github.com/glpi-project/glpi/commit/10a827c8c1868a0a65ab977d30878ff16547d9a7"},{"type":"FIX","url":"https://github.com/glpi-project/glpi/commit/d30faa501e8b549ae507615b05e7d99dacfe5d98"},{"type":"ADVISORY","url":"https://github.com/glpi-project/glpi/security/advisories/GHSA-c46f-4v9j-5gpc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-121559"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/glpi-10.0.0-before-10.0.28-and-11.0.0-before-11.0.10-privilege-escalation-via-user-cloning"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-11-04T10:30:55.360870970Z"}}
