{"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":"2026-08-12T03:51:34.050154376Z","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"},{"fixed":"0e56382921fc71e64829cd1ec35f04e338c70917"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"26.0"}]}}],"versions":["25.0","24.0","22.0","21.0","18.0","14.3.1","14.3","12.4","11.6","11.5","11.1.1","11.1","11","10.8","8.9.1","8.9","8.7","8.6","8.5","8.1","7.8","7.7","7.6","7.4","7.3","7.2","4.0","3.4","2.7","2.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33039.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N"}]}
