WWBN AVideo is an open source video platform. In versions up to and including 26.0, the function in AVideo can be bypassed using IPv4-mapped IPv6 addresses ( ). The unauthenticated 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.
