## Description

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.

## Affected Products

- Keycloak — keycloak (0)
- Red Hat — Red Hat build of Keycloak 26.4 (26.4.4-1)
- Red Hat — Red Hat build of Keycloak 26.4 (26.4-3)
