NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak package and not the keycloak package as distributed by Chainguard. See How to fix? for Chainguard 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.
