{"id":"CVE-2026-114634","summary":"WWBN AVideo before 29.4.0 Blind SSRF via getHeaderContentTypeFromURL Redirect","details":"WWBN AVideo before 29.4.0 contains a blind server-side request forgery vulnerability in getHeaderContentTypeFromURL() because get_headers() follows redirects without re-validating targets with isSSRFSafeURL(). Authenticated uploaders can store a videoLink pointing to a redirector, causing internal GET requests when visitors view the video, enabling internal port scanning via the embed-versus-video render oracle.","aliases":["GHSA-m8q2-35pq-qrmc"],"modified":"2026-10-22T10:46:03.009342292Z","published":"2026-10-22T01:43:35.830Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114634.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114634.json"},{"type":"FIX","url":"https://github.com/WWBN/AVideo/commit/2db920d3326729743511a27de44034b0a6c78b05"},{"type":"ADVISORY","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-m8q2-35pq-qrmc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114634"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/wwbn-avideo-before-29.4.0-blind-ssrf-via-getheadercontenttypefromurl-redirect"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wwbn/avideo","events":[{"introduced":"0"},{"fixed":"a76721723acd72dae306cc58c4931e1193b90f8d"},{"fixed":"2db920d3326729743511a27de44034b0a6c78b05"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"29.4.0"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"},{"range":[{"fixed":"2db920d3326729743511a27de44034b0a6c78b05"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["v29.3.0","v29.2.0","v29.1.1","v29.1.0","29.0","26.0","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-2026-114634.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:L/SI:L/SA:L"}]}
