From 8.36 until 9.74, the outgoing webhook Integration URL validator in models/integrations.js checked only the literal URL.hostname against regular expressions, so DNS names such as 169-254-169-254.nip.io passed that first-line check. The delivery path's fetchSafe guard already blocked the reported IPv4 destination, but its separate IPv4-only resolver and duplicated blocklist created inconsistent all-address-family enforcement and drift risk between input-time and connection-time validation. Version 9.74 makes server/lib/ssrfGuard.js resolve all addresses with `dns.lookup({ all: true })`, validate every result through the shared isIpBlocked logic, pin the connection, and block redirects. This issue is fixed in version 9.74.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":47,"depthScoreParts":{"impact":46.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
