{"id":"CVE-2026-73661","aliases":["GHSA-f6hc-rqxg-ch86"],"url":"https://o3.security/vulnerability/CVE-2026-73661","summary":"FreePBX: Authenticated Framework AUTHTYPE Can Be Restored From a Crafted Backup","details":"FreePBX is an open source IP PBX. Prior to 16.0.47 and 17.0.30, the FreePBX Framework module permits a crafted backup to restore the hidden AUTHTYPE setting with the value none through runRestore() in amp_conf/htdocs/admin/libraries/Builtin/Restore.php. An authenticated user with sufficient backup-restore access or write access to backup files can thereby disable FreePBX authentication during restoration, bypassing the user-interface removal of AUTHTYPE=none. This issue is fixed in versions 16.0.47 and 17.0.30.","published":"2026-08-13T21:25:26.136Z","modified":"2026-08-15T04:07:16.410068977Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/FreePBX/framework/commit/0591581654bc269df05cbb7093645d6934d4d861","label":"FreePBX/framework@0591581"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73661.json"},{"type":"FIX","url":"https://github.com/FreePBX/framework/commit/0591581654bc269df05cbb7093645d6934d4d861"},{"type":"FIX","url":"https://github.com/FreePBX/framework/commit/ea684be89abb393d1aff7f979d5fd751ff338dfd"},{"type":"ADVISORY","url":"https://github.com/FreePBX/security-reporting/security/advisories/GHSA-f6hc-rqxg-ch86"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73661"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-15T04:07:16.410068977Z"}}
