Description
snipe-it versions before 8.7.0 contain a server-side request forgery vulnerability in the ExternalUrl validation rule that fails to detect IPv6 transition addresses encoding private IPv4 targets. Attackers with super-admin privileges can configure webhook URLs using NAT64, 6to4, or Teredo transition addresses to bypass SSRF guards and access internal services or cloud metadata endpoints.
