CVE-2026-19729

Keycloak-services: keycloak-services: incomplete fix for arbitrary filesystem path probing via keystore parameters

Published Sep 9, 2026 CVSS 3.1 · 4.9 Medium EPSS < 1% KEV · Not listed
Description
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.
