CVE-2026-33480Public exploitNetwork attack vector

Unauthenticated internal resource disclosure via IPv4-mapped IPv6 bypass

Published Mar 23, 2026 · Updated Mar 23, 2026

SSRF in AVideo 26.0 and earlier allows remote attackers to read internal resources through the unauthenticated LiveLinks proxy. The isSSRFSafeURL function treats mapped addresses as IPv6, so its IPv4 private-range regexes and IPv6 blocklist both miss the embedded address. Anonymous requests to plugin/LiveLinks/proxy.php can make curl fetch cloud metadata, localhost, or internal services and return the response.
