{"id":"CVE-2026-33038","aliases":["GHSA-2f9h-23f7-8gcx"],"url":"https://o3.security/vulnerability/CVE-2026-33038","summary":"AVideo affected by unauthenticated application takeover via exposed web installer on uninitialized deployments","details":"WWBN AVideo is an open source video platform. Versions 25.0 and below are vulnerable to unauthenticated application takeover through the install/checkConfiguration.php endpoint. install/checkConfiguration.php performs full application initialization: database setup, admin account creation, and configuration file write, all from an unauthenticated POST input. The only guard is checking whether videos/configuration.php already exists. On uninitialized deployments, any remote attacker can complete the installation with attacker-controlled credentials and an attacker-controlled database, gaining full administrative access. This issue has been fixed in version 26.0.","published":"2026-03-20T05:35:56.812Z","modified":"2026-08-12T03:51:18.661715577Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":null}],"fix":{"url":"https://github.com/WWBN/AVideo/commit/b3fa7869dcb935c8ab5c001a88dc29d2f92cf8e1","label":"WWBN/AVideo@b3fa786"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33038.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-2f9h-23f7-8gcx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33038"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/b3fa7869dcb935c8ab5c001a88dc29d2f92cf8e1"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:18.661715577Z"}}
