Machine-written summary

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

Maven package nl.nl-portal:documenten-api versions before 3.0.3 let any logged-in user download the contents of documents belonging to other people, by requesting a document identifier through the REST content endpoint or the getDocumentContent GraphQL query. This is a follow-up to CVE-2026-49463, whose fix in 3.0.1 was incomplete. Upgrade to 3.0.3, where both endpoints were removed; if you cannot upgrade, block the content endpoint and the getDocumentContent query at your gateway or proxy.
