CVE-2026-93597Public exploitNetwork attack vectorHinoki check available

Authenticated SSRF via unchecked IPv6 transition addresses

Published Sep 18, 2026 · Updated Sep 18, 2026

Server-side request forgery in ArcadeDB before 26.9.1 allows remote authenticated users to read internal HTTP resources via crafted URLs. The ImportSecurityValidator.isBlockedAddress and PostServerCommandHandler.isBlockedHost guards trust Java address flags without extracting private IPv4 payloads embedded in NAT64, 6to4, or Teredo addresses. Exploitation requires import or restore permission, attacker-controlled DNS, and a compatible IPv6 network path; successful requests expose internal services or cloud metadata.
