CVE-2026-19729: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Red Hat Red Hat Build of Keycloak
CVE-2026-19729 is a path traversal vulnerability in the key provider component of the keycloak-services library used by the Red Hat Build of Keycloak. A previous fix for path probing was incomplete, allowing a realm administrator to submit arbitrary filesystem paths as keystore parameters. This can be exploited to check the existence and readability of files on the server, potentially exposing sensitive system information. The vulnerability has a CVSS score of 4.9, indicating medium severity. No specific affected versions or patch information are provided in the available data.
AI Analysis
Technical Summary
This vulnerability arises from an incomplete fix in the key provider component of the keycloak-services library in Red Hat Build of Keycloak. It allows a realm administrator to perform path traversal by submitting arbitrary filesystem paths as keystore parameters. This can be used to determine the existence and readability of files on the server, potentially leaking sensitive information. The issue does not impact integrity or availability but has a confidentiality impact. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, no user interaction, and unchanged scope.
Potential Impact
An attacker with realm administrator privileges can leverage this vulnerability to probe arbitrary filesystem paths on the server, potentially exposing sensitive system information. The confidentiality of the system is impacted, but integrity and availability are not affected. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://access.redhat.com/security/cve/CVE-2026-19729 for current remediation guidance. Since no remediation level or patch links are provided, users should monitor the vendor advisory for updates and apply official fixes once available.
