Summary
Wekan: SSRF filter bypass via DNS-resolving hostname in outgoing webhooks (incomplete fix of CVE-2026-53446)
Details

Wekan is open source kanban built with Meteor. 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.
