      "value": "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."

      "value": "Wekan es un kanban de código abierto construido con Meteor. Desde la versión 8.36 hasta la 9.74, el validador de URL de integración de webhook saliente en models/integrations.js comprobaba solo el URL.hostname literal contra expresiones regulares, por lo que nombres DNS como 169-254-169-254.nip.io pasaban esa comprobación de primera línea. La protección fetchSafe de la ruta de entrega ya bloqueaba el destino IPv4 reportado, pero su resolutor separado solo para IPv4 y su lista de bloqueo duplicada crearon una aplicación inconsistente para todas las familias de direcciones y un riesgo de deriva entre la validación en tiempo de entrada y en tiempo de conexión. La versión 9.74 hace que server/lib/ssrfGuard.js resuelva todas las direcciones con dns.lookup({ all: true }), valide cada resultado a través de la lógica compartida isIpBlocked, fije la conexión y bloquee las redirecciones. Este problema está solucionado en la versión 9.74."
