The issue occurs when a user with the view-clients role accesses the client registration endpoint to retrieve client details. Due to a failure to mask sensitive information, the service returns the client's confidential secret in cleartext. This could allow a read-only administrator to obtain full access to the affected client's account and potentially escalate their privileges within the realm."}],"affected":[{"vendor":"Red Hat","product":"Red Hat Build of Keycloak","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"keycloak/rhbk-openshift-rhel9","defaultStatus":"affected","cpes":["cpe:/a:redhat:build_keycloak:"]},{"vendor":"Red Hat","product":"Red Hat Build of Keycloak","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"keycloak-services","defaultStatus":"affected","cpes":["cpe:/a:redhat:build_keycloak:"]},{"vendor":"Red Hat","product":"Red Hat Build of Keycloak","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"rhbk/keycloak-rhel9","defaultStatus":"affected","cpes":["cpe:/a:redhat:build_keycloak:"]},{"vendor":"Red Hat","product":"Red Hat Single Sign-On 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"keycloak-services","defaultStatus":"affected","cpes":["cpe:/a:redhat:red_hat_single_sign_on:7"]}],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-89298","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2531871","name":"RHBZ#2531871","tags":["issue-tracking","x_refsource_REDHAT"]}],"datePublic":"2026-09-10T19:03:32.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-200","description":"Exposure of Sensitive Information to an Unauthorized Actor","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-200: Exposure of Sensitive Information to an Unauthorized Actor","workarounds":[{"lang":"en","value":"Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability."}],"timeline":[{"lang":"en","time":"2026-09-10T19:03:32.000Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-09-10T19:03:32.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"Red Hat would like to thank Animesh Roy (Anir0y) for reporting this issue."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-09-11T13:25:24.218Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-11T14:52:15.544171Z","id":"CVE-2026-89298","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-11T14:55:17.101Z"}}]}}
