CVE-2026-33480

CVE-2026-33480 · AVideo has a SSRF Protection Bypass via IPv4-Mapped IPv6 Addresses in Unauthenticated LiveLinks Proxy

This page contains facts from public vulnerability sources. Check the original advisory before updating.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `isSSRFSafeURL()` function in AVideo can be bypassed using IPv4-mapped IPv6 addresses (`::ffff:x.x.x.x`). The unauthenticated `plugin/LiveLinks/proxy.php` endpoint uses this function to validate URLs before fetching them with curl, but the IPv4-mapped IPv6 prefix passes all checks, allowing an attacker to access cloud metadata services, internal networks, and localhost services. Commit 75ce8a579a58c9d4c7aafe453fbced002cb8f373 contains a patch.
