CVE-2026-82648Public exploitNetwork attack vectorHinoki check available

Internal data disclosure via hexadecimal NAT64 bypass

Published Aug 30, 2026 · Updated Aug 30, 2026

SSRF in WWBN AVideo allows remote authenticated users to read internal service responses via hexadecimal NAT64 URL addresses. The isSSRFSafeURL function matches only dotted-decimal NAT64 tails, leaves equivalent hexadecimal IPv6 literals unnormalized, and passes them to PHP as public addresses. An account able to upload and edit a video and a deployment with a working NAT64 path are required; fetched metadata or loopback content can be recovered from the generated thumbnail.
