{"id":"CVE-2026-33039","summary":"AVideo vulnerable to unauthenticated SSRF via HTTP redirect bypass in LiveLinks proxy","details":"WWBN AVideo is an open source video platform. In versions 25.0 and below, the plugin/LiveLinks/proxy.php endpoint validates user-supplied URLs against internal/private networks using isSSRFSafeURL(), but only checks the initial URL. When the initial URL responds with an HTTP redirect (Location header), the redirect target is fetched via fakeBrowser() without re-validation, allowing an attacker to reach internal services (cloud metadata, RFC1918 addresses) through an attacker-controlled redirect. This issue is fixed in version 26.0.","aliases":["GHSA-9x67-f2v7-63rw"],"modified":"2026-04-02T13:26:45.235054Z","published":"2026-03-20T05:38:50.912Z","database_specific":{"cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33039.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33039.json"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-9x67-f2v7-63rw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33039"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/0e56382921fc71e64829cd1ec35f04e338c70917"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"aee1e11ee8d9343f87b7643e49cc32924b07979b"}]}],"versions":["10.4","10.8","11","11.1","11.1.1","11.5","11.6","12.4","14.3","14.3.1","14.4","18.0","2.2","2.4","2.7","21.0","22.0","24.0","25.0","3.4","3.4.1","4.0","4.0.1","4.0.2","5.0","6.5","7.2","7.3","7.4","7.5","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-2026-33039.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N"}]}
