CVE-2026-53573: core-geonetwork has an Open Redirect Bypass
GeoNetwork’s post-login redirect handling can be bypassed to redirect users to an attacker-controlled external site, even though the code attempts to restrict redirect targets to relative, in-application URLs. This affects both supported SSO login methods: OAuth2/OIDC and Keycloak.
