What is CVE-2024-11736?

A configuration exposure vulnerability has been identified in Keycloak that allows admin users to access sensitive server environment variables and system properties through crafted user-configurable URLs. By manipulating backchannel logout URLs or admin URLs using placeholders like ${env.VARNAME} or ${PROPNAME}, administrators can inadvertently disclose critical server information, as the server processes and substitutes these placeholders with their actual values. This vulnerability poses a significant risk, particularly if the exposed variables contain sensitive data.
