FKIE_CVE-2025-10939
Vulnerability from fkie_nvd - Published: 2025-10-28 04:16 - Updated: 2026-06-17 08:29
Severity
Summary
A flaw was found in Keycloak. The Keycloak guides recommend to not expose /admin path to the outside in case the installation is using a proxy. The issue occurs at least via ha-proxy, as it can be tricked to using relative/non-normalized paths to access the /admin application path relative to /realms which is expected to be exposed.
