CVE-2026-53573 (GCVE-0-2026-53573)

Vulnerability from cvelistv5 – Published: 2026-07-31 22:16 – Updated: 2026-07-31 22:16

Title

core-geonetwork has an Open Redirect Bypass

Summary

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.

Severity

4.8 (Medium)

Vulnerability from github – Published: 2026-07-31 22:16 – Updated: 2026-07-31 22:16

Summary

core-geonetwork has an Open Redirect Bypass

Details

Summary

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.

Details

Both the OAuth2/OIDC and Keycloak login filters validate the client-supplied post-login redirect target before forwarding the browser to it, but the validation does not correctly reject every kind of URL that causes the browser to leave the GeoNetwork origin. As a result, a value that is treated as a safe, in-application relative path by the filter can still cause the browser to be redirected to an external, attacker-controlled host.

Impact

An attacker can craft a link to a legitimate GeoNetwork OAuth2/OIDC or Keycloak login endpoint that, after the login flow completes, redirects the victim to an arbitrary external site. This can be used for phishing (e.g., presenting a fake login form) or to chain into other attacks hosted externally. This does not bypass authentication or expose GeoNetwork data directly; the impact is Open Redirect (CWE-601).

GeoNetwork 3.x and 4.0.x are archived/unmaintained and will not receive a fix for this issue. Instances running those lines should upgrade to a supported release (4.2.16 or later, or 4.4.11 or later).
