What is CVE-2026-19729?

A vulnerability exists in the key provider component of the keycloak-services library, which serves as the core engine for the Red Hat Build of Keycloak. This flaw arises from an incomplete previous update concerning path probing. As a consequence, a realm administrator can still submit arbitrary filesystem paths as keystore parameters. This misconfiguration could enable the unauthorized determination of file existence and readability on the server, thereby risking the exposure of sensitive information stored in the filesystem.
