CVE-2026-19729— Keycloak-services: keycloak-services: incomplete fix for arbitrary filesystem path probing via keystore parameters

Quick assessment

Affected
Red Hat Red Hat build of Keycloak 26.4
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Keycloak是Keycloak组织开源的一款身份认证与权限管理平台。 Keycloak存在路径遍历漏洞，该漏洞源于key provider组件中路径探测修复不完整，允许领域管理员提交任意文件系统路径作为keystore参数，从而判断服务器上文件的存在性和可读性，可能泄露敏感系统信息。

Vulnerability Title
Keycloak-services: keycloak-services: incomplete fix for arbitrary filesystem path probing via keystore parameters
Source: CVE Program / CVE List V5
Vulnerability 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.
