{"id":"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.","aliases":["GHSA-2f9h-23f7-8gcx"],"modified":"2026-04-10T05:42:34.719920Z","published":"2026-03-20T05:35:56.812Z","database_specific":{"cwe_ids":["CWE-306"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33038.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"aee1e11ee8d9343f87b7643e49cc32924b07979b"}]}],"versions":["10.8","11","11.1","11.1.1","11.5","11.6","12.4","14.3","14.3.1","18.0","2.2","2.7","21.0","22.0","24.0","25.0","3.4","4.0","7.2","7.3","7.4","7.6","7.7","7.8","8.1","8.5","8.6","8.7","8.9","8.9.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33038.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
