Lifecycle Timeline
1DescriptionCVE.org
A flaw was found in Keycloak. A realm administrator with the "manage-realm" role can exploit this vulnerability by submitting an arbitrary filesystem path as a keystore parameter when creating a key provider component. This allows the administrator to probe arbitrary filesystem paths, determining which files exist and are readable by the Keycloak process. This information disclosure could be used to identify high-value targets for follow-on attacks.
AnalysisAI
Red Hat Build of Keycloak allows realm administrators holding the 'manage-realm' role to probe arbitrary filesystem paths by submitting unsanitized path values as keystore parameters during key provider component creation. The Keycloak process's file access attempt reveals whether a given path exists and is readable, functioning as a filesystem oracle for authenticated attackers. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated session with realm administrator privileges specifically holding the 'manage-realm' role within the target Keycloak realm. … 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 base score of 4.9, which accurately reflects a meaningful but constrained risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A threat actor who has obtained realm administrator credentials (via phishing, credential stuffing, or insider access) authenticates to the Keycloak admin API and issues a key provider creation request with the keystore path set to a target such as '/etc/keycloak/standalone/configuration/standalone.xml' or '/root/.ssh/id_rsa'. The Keycloak process attempts to open the specified file, and the API response - whether an error message or a successful parse attempt - reveals whether the file exists and is readable by the Keycloak service account. … |
| Remediation | Consult the Red Hat Security Advisory at https://access.redhat.com/security/cve/CVE-2026-9083 for the official patch; a specific fixed version number was not confirmed in the provided input data, so a precise upgrade target cannot be stated here. … Detailed patch versions, workarounds, and compensating controls in full report. |
