CVE-2024-11736Network attack vectorHinoki check available

Server secret disclosure via unrestricted placeholder expansion

Published Jan 14, 2025 · Updated Aug 31, 2026

Information disclosure in Keycloak before 26.0.8 allows remote authenticated users with admin rights to read server secrets via crafted URLs. URL processing passes admin-configured backchannel logout and admin URLs to StringPropertyReplacer, which resolves placeholders from an unrestricted server property source. Administrative access is required; the consequence is confidentiality loss for environment variables or system properties exposed to the server process, including the affected Red Hat build.
