Descriptions

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.

New images are available for Red Hat build of Keycloak 26.4.4 and Red Hat build of Keycloak 26.4.4 Operator, running on OpenShift Container Platform.

*Credits: Red Hat would like to thank Sebastian Reigber (AEB) for reporting this issue.
