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.","score":4.2,"severity":"medium","published":"2026-09-19T14:09:11.811Z","modified":"2026-11-06T17:34:22.181Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Red Hat","name":"Red Hat build of Keycloak 26.6","platforms":[],"versions":[{"version":"26.6.8-2","status":"unaffected","lessThan":"*","versionType":"rpm"}],"defaultStatus":"affected","cpes":["cpe:/a:redhat:build_keycloak:26.6::el9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93999"},{"vendor":"Red Hat","name":"Red Hat build of Keycloak 26.6","platforms":[],"versions":[{"version":"26.6-24","status":"unaffected","lessThan":"*","versionType":"rpm"}],"defaultStatus":"affected","cpes":["cpe:/a:redhat:build_keycloak:26.6::el9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93999"},{"vendor":"Red Hat","name":"Red Hat build of Keycloak 26.6","platforms":[],"versions":[{"version":"26.6-24","status":"unaffected","lessThan":"*","versionType":"rpm"}],"defaultStatus":"affected","cpes":["cpe:/a:redhat:build_keycloak:26.6::el9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93999"},{"vendor":"Red Hat","name":"Red Hat build of Keycloak 26.6.8","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/a:redhat:build_keycloak:26.6::el9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93999"},{"vendor":"Red Hat","name":"Red Hat build of Keycloak 26.6.8","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/a:redhat:build_keycloak:26.6::el9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93999"},{"vendor":"Red Hat","name":"Red Hat build of Keycloak 26.6.8","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/a:redhat:build_keycloak:26.6::el9"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93999"},{"vendor":"Red Hat","name":"Red Hat Single Sign-On 7","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/a:redhat:red_hat_single_sign_on:7"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93999"}],"remediation":[{"text":"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.","source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-93999"}],"references":["https://access.redhat.com/errata/RHSA-2026:95761","https://access.redhat.com/errata/RHSA-2026:95762","https://access.redhat.com/security/cve/CVE-2026-93999","https://bugzilla.redhat.com/show_bug.cgi?id=2537165"],"sources":[{"name":"CVE","id":"CVE-2026-93999","modified":"2026-11-06T17:34:22.181Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-93999"}],"assessments":[{"source":"redhat","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","score":4.2}],"sourceAffected":[],"observedAt":"2026-11-06T17:56:32.557Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T03:40:34.262Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-06T13:30:35.679Z","attemptedAt":"2026-11-06T13:30:35.679Z"},{"source":"GHSA","status":"available","checkedAt":"2026-11-06T13:30:36.224Z","attemptedAt":"2026-11-06T13:30:36.224Z"},{"source":"EUVD","status":"available","checkedAt":"2026-11-06T13:30:36.437Z","attemptedAt":"2026-11-06T13:30:36.437Z"},{"source":"EPSS","status":"available","checkedAt":"2026-11-06T13:30:35.316Z","attemptedAt":"2026-11-06T13:30:35.316Z"}],"evidence":[{"source":"FIRST EPSS","id":"CVE-2026-93999","url":"https://www.first.org/epss/","probability":0.00227,"percentile":0.13564,"date":"2026-11-05","checkedAt":"2026-11-06T13:30:35.316Z"},{"source":"NVD","id":"CVE-2026-93999","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93999","modified":"2026-11-06T11:17:21.247","score":4.2,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","checkedAt":"2026-11-06T13:30:35.679Z"},{"source":"GitHub Advisory Database","id":"GHSA-82wc-7jr6-wxgm","url":"https://github.com/advisories/GHSA-82wc-7jr6-wxgm","modified":"2026-11-06T12:31:35Z","score":4.2,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","checkedAt":"2026-11-06T13:30:36.224Z"},{"source":"ENISA EUVD","id":"EUVD-2026-83600","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-83600","modified":"Nov 6, 2026, 10:26:11 AM","score":4.2,"vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","checkedAt":"2026-11-06T13:30:36.437Z"}],"aiSummary":{"text":"A flaw in Keycloak's OIDC protocol implementation allows an application with an existing refresh token to obtain valid access tokens for a disabled client.
