ArcadeDB versions before 26.9.1 fail to validate IPv6 transition addresses in the SSRF guard used by IMPORT DATABASE and server commands. Authenticated attackers can supply URLs resolving to NAT64, 6to4, or Teredo addresses embedding RFC 1918 or loopback IPv4 payloads to reach internal services and cloud metadata endpoints.
