description

GeoNetwork 4.x search handling can fail to apply visibility and access-control restrictions to Elasticsearch requests. An unauthenticated remote user may read indexed metadata that should be restricted when the public search API receives an affected request form.

mitigation

Upgrade core-geonetwork to 4.2.16 or 4.4.11, as appropriate for your release branch. Until upgrading, restrict unauthenticated access to the public search API.

fixed in 4.2.16, 4.4.11
