CVE-2026-19729

A flaw was found in the key provider component of the keycloak-services library, which is the core engine for the Red Hat Build of Keycloak. The issue occurs because a previous fix for path probing was incomplete, allowing a realm administrator to still submit arbitrary filesystem paths as keystore parameters. This can be used to determine the existence and readability of files on the server, potentially exposing sensitive system information.
