Lifecycle Timeline
1DescriptionCVE.org
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.
AnalysisAI
Path traversal in the key provider component of Red Hat Build of Keycloak allows a realm administrator to probe arbitrary filesystem paths by supplying crafted keystore parameters, revealing the existence and readability of server-side files. The vulnerability exists because a prior fix for path probing was incomplete, leaving a residual bypass in the keycloak-services library - the core engine shared by both Red Hat Build of Keycloak and Red Hat Single Sign-On 7. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid realm administrator account in the target Keycloak deployment. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N yields a score of 4.9 (Medium), and the metric choices are well-calibrated: PR:H (realm administrator required) is the critical limiting factor that prevents this from being a high-priority mass-exploitation target. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Patch available per vendor advisory - apply the updated keycloak-services package from Red Hat as soon as it is released for your subscription channel (see https://access.redhat.com/security/cve/CVE-2026-19729 for errata details). … Detailed patch versions, workarounds, and compensating controls in full report. |
