Machine-written summary

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

GHSA-qpm9-h556-mwxm affects nl.nl-portal:documenten-api before 3.0.1 and nl.nl-portal:besluiten from 1.5.0 up to 3.0.1 excluded. A logged-in user could retrieve the content of any document by ID, and list, search and read decision records belonging to other users, which can contain sensitive personal data. Upgrade to 3.0.1 or later; in 3.0.1 the besluiten module is removed, so replacement functionality must be built with per-user checks first. Where upgrading is not possible, the source suggests blocking the affected GraphQL operations at the API gateway.
