The issue occurs during the token refresh process when the server restores requested audiences from stored client IDs. Keycloak fails to verify if the target audience client is still enabled before issuing a new access token. This allows an application with an existing refresh token to continue obtaining valid access tokens for a disabled client, potentially bypassing administrative access controls for resource servers that rely on offline JWT validation.","state":"PUBLISHED","assigner":"redhat","published_at":"2026-09-19 15:17:08","updated_at":"2026-09-19 15:17:08"},"problem_types":["CWE-862","CWE-862 Missing Authorization"],"metrics":[{"version":"3.1","source":"secalert@redhat.com","type":"Primary","score":"4.2","severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","data":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","baseScore":4.2,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"}},{"version":"3.1","source":"CNA","type":"CVSS","score":"4.2","severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","data":{"attackComplexity":"HIGH","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":4.2,"baseSeverity":"MEDIUM","confidentialityImpact":"LOW","integrityImpact":"LOW","privilegesRequired":"LOW","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"}}],"references":[{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2537165","name":"https://bugzilla.redhat.com/show_bug.cgi?id=2537165","refsource":"secalert@redhat.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://access.redhat.com/security/cve/CVE-2026-93999","name":"https://access.redhat.com/security/cve/CVE-2026-93999","refsource":"secalert@redhat.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-93999","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93999","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"Red Hat","product":"Red Hat Build of Keycloak","version":"","platforms":[]},{"source":"CNA","vendor":"Red Hat","product":"Red Hat Build of Keycloak","version":"","platforms":[]},{"source":"CNA","vendor":"Red Hat","product":"Red Hat Build of Keycloak","version":"","platforms":[]},{"source":"CNA","vendor":"Red Hat","product":"Red Hat Single Sign-On 7","version":"","platforms":[]}],"timeline":[{"source":"CNA","time":"2026-09-18T01:00:50.000Z","lang":"en","value":"Reported to Red Hat."},{"source":"CNA","time":"2026-09-18T01:00:50.000Z","lang":"en","value":"Made public."}],"solutions":[],"workarounds":[{"source":"CNA","title":"","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.","time":"","lang":"en"}],"exploits":[],"credits":[{"source":"CNA","value":"Red Hat would like to thank Moritz Theile (@Moritz-cmd) for reporting this issue.","lang":"en"}],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"cna":{"affected":[{"collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/a:redhat:build_keycloak:"],"defaultStatus":"affected","packageName":"keycloak/rhbk-openshift-rhel9","product":"Red Hat Build of Keycloak","vendor":"Red Hat"},{"collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/a:redhat:build_keycloak:"],"defaultStatus":"affected","packageName":"keycloak-services","product":"Red Hat Build of Keycloak","vendor":"Red Hat"},{"collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/a:redhat:build_keycloak:"],"defaultStatus":"affected","packageName":"rhbk/keycloak-rhel9","product":"Red Hat Build of Keycloak","vendor":"Red Hat"},{"collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/a:redhat:red_hat_single_sign_on:7"],"defaultStatus":"unaffected","packageName":"keycloak-services","product":"Red Hat Single Sign-On 7","vendor":"Red Hat"}],"credits":[{"lang":"en","value":"Red Hat would like to thank Moritz Theile (@Moritz-cmd) for reporting this issue."}],"datePublic":"2026-09-18T01:00:50.000Z","descriptions":[{"lang":"en","value":"A flaw was found in the OIDC protocol implementation of Keycloak, an open-source identity and access management solution.
