Upstream source description

WeKnora before 0.8.2 contains a server-side request forgery vulnerability in isRestrictedIP() that misclassifies NAT64-prefixed IPv6 addresses as public. Authenticated attackers can supply URLs resolving to NAT64 encodings of internal addresses via web_fetch or URL-based knowledge import to reach internal services or cloud metadata endpoints.
