Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-xm3x-9cfw-jhx4 affects the Maven package nl.nl-portal:form, versions 1.1.0 up to but not including 3.0.4. An unauthenticated caller of a public GraphQL resolver can make the backend send the privileged Objecten-API token to a caller-chosen URL on the configured Objecten-API host, a constrained server-side request forgery. Upgrade to 3.0.4 or later; the fix removes the unauthenticated resolvers, and the frontend libraries must also be upgraded to v3.0.3 or later because of breaking query changes.
