CVE-2026-53573
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.
Does this matter?
Lower severity and a low EPSS score (0.38%). Track it; it rarely justifies an emergency change on its own.
