{"apiVersion":"1.0","identifier":"CVE-2026-73661","description":"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.","publishedAt":"2026-08-13T22:17:27","lastModifiedAt":"2026-08-14T19:18:01","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73661","cvssScore":8.6,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00335,"riskScore":0.89,"affectedProduct":"FreePBX","affectedVersions":"<16.0.47, <17.0.30","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-73661","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-73661","en":"https://www.redsauce.net/en/cves/CVE-2026-73661","fr":"https://www.redsauce.net/fr/cves/CVE-2026-73661","pt":"https://www.redsauce.net/pt/cves/CVE-2026-73661","de":"https://www.redsauce.net/de/cves/CVE-2026-73661","sk":"https://www.redsauce.net/sk/cves/CVE-2026-73661","el":"https://www.redsauce.net/el/cves/CVE-2026-73661"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-73661"}}
