CVE-2026-91966Network attack vectorHinoki check available

Unauthenticated SSRF via trusted Host header

Published Sep 15, 2026 · Updated Sep 15, 2026

SSRF in AVideo through 29.0 allows remote attackers to probe internal hosts and ports through unauthenticated web requests. The check_site_availability function treats the HTTP Host header as a destination and follows redirects without restricting internal addresses. No account is required; requests to submitIndex.php or ajax.php can make the server test attacker-selected network endpoints.
