{"id":"CVE-2026-88959","summary":"Anchor CMS through 0.12.7 Privilege Escalation via Missing Authorization on Admin User-Management Endpoints","details":"Anchor CMS through 0.12.7 fails to enforce role-based access control in admin user-management endpoints, allowing any authenticated low-privilege user to create administrator accounts or modify existing ones. Attackers with editor or user roles can POST directly to admin/users/add or admin/users/edit endpoints to create new administrator accounts or change the existing administrator's password, gaining full administrative access.","modified":"2026-09-12T11:30:14.277740563Z","published":"2026-09-10T15:44:12.945Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88959.json"},"references":[{"type":"WEB","url":"https://packagist.org"},{"type":"ADVISORY","url":"https://gist.github.com/bozorovab2009-spec/57931237f774b78333f8fe47e84ec4aa"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88959.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-88959"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/anchor-cms-through-0.12.7-privilege-escalation-via-missing-authorization-on-admin-user-management-endpoints"},{"type":"PACKAGE","url":"https://github.com/anchorcms/anchor-cms"},{"type":"ARTICLE","url":"https://github.com/anchorcms/anchor-cms/blob/0.12.7/anchor/routes/users.php"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/anchorcms/anchor-cms","events":[{"introduced":"0"},{"fixed":"08e8e507909ee55b588674563b8ea21646ed9425"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"0.12.7"},{"fixed":"0.12.7"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["0.12.6","0.12.3a","0.12.3","0.12.1","0.12","0.9.3.1-a","0.9.1","0.9","0.8.2","0.8.1","0.8","0.7.2","0.7","0.6","0.5","0.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-88959.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
