AVideo before 24.0 contains a server-side request forgery vulnerability in the isSSRFSafeURL function that fails to extract embedded IPv4 addresses from NAT64, 6to4, and Teredo IPv6 transition address formats. Unauthenticated attackers can bypass SSRF protections via the LiveLinks proxy endpoint to reach internal services and cloud metadata endpoints by encoding private IPv4 targets in transition address formats.
