CVE-2026-46487 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. GeoNetwork is a catalog application to manage spatially referenced resources. From 4.0.0-alpha.1 until 4.2.16 and 4.4.11, the Elasticsearch-backed search proxy can skip GeoNetwork's access-control filter injection when a client request has an omitted query field. EPSS estimates a 0.46% chance of exploitation in the next 30 days.

Description

GeoNetwork is a catalog application to manage spatially referenced resources. From 4.0.0-alpha.1 until 4.2.16 and 4.4.11, the Elasticsearch-backed search proxy can skip GeoNetwork's access-control filter injection when a client request has an omitted query field. The request is then forwarded to Elasticsearch without group visibility, draft exclusion, record ownership, or portal-specific filtering. An unauthenticated remote attacker can use the affected public search API to retrieve the full indexed contents of metadata records that should not be publicly visible. This issue is fixed in versions 4.2.16 and 4.4.11.
