NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak-25 package and not the keycloak-25 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

A vulnerability was found in Keycloak. Admin users may have to access sensitive server environment variables and system properties through user-configurable URLs. When configuring backchannel logout URLs or admin URLs, admin users can include placeholders like ${env.VARNAME} or ${PROPNAME}. The server replaces these placeholders with the actual values of environment variables or system properties during URL processing.
