MEDIUMPre-NVD 4.84.8—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 4.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 68% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

GeoNetwork is a catalog application to manage spatially referenced resources. From 3.12.0 until 4.2.16 and 4.4.11, unsafe redirect validation in GeonetworkOAuth2LoginAuthenticationFilter and KeycloakAuthenticationProcessingFilter permits an attacker-controlled external redirect after login. This issue is fixed in versions 4.2.16 and 4.4.11.
