{"id":"CVE-2026-33039","aliases":["GHSA-9x67-f2v7-63rw"],"url":"https://o3.security/vulnerability/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.","published":"2026-03-20T05:38:50.912Z","modified":"2026-08-07T11:50:53.201584642Z","cvss":{"score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"wwbn/avideo","fixedVersion":null}],"fix":{"url":"https://github.com/WWBN/AVideo/commit/0e56382921fc71e64829cd1ec35f04e338c70917","label":"WWBN/AVideo@0e56382"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:53.201584642Z"}}
