What is CVE-2026-82648?

The WWBN AVideo platform contains a vulnerability in the isSSRFSafeURL function that allows attackers to bypass existing server-side request forgery (SSRF) protections. This failure occurs due to the inability of the system to properly normalize NAT64 addresses provided in hexadecimal format. Attackers can exploit this oversight by supplying hex-encoded NAT64 addresses, such as 64:ff9b::a9fe:a9fe, which can allow unauthorized access to cloud metadata services and loopback interfaces, posing a significant security risk.
