Description
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.
