A bug in the response serialization causes the backchannel logout offline token revocation setting to be omitted from responses. When a client performs a standard update, this missing information causes the setting to be silently disabled. As a result, offline tokens may remain valid even after a user session is terminated via backchannel logout.","epss":{"date":"2026-11-05","percentile":0.04988,"score":0.00158},"exploits":[],"kev":null,"metrics":[{"score":4.3,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},{"score":4.3,"severity":"medium","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"}],"modifiedAt":1793963823547,"publishedAt":1791470375945,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95761"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-107623"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2547957"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95761"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-107623"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2547957"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","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."}],"revision":"c0071c584ab6adfea7bc43f19ca72eae21fac51ec4cb08de271141fc70ff69c7","sources":[{"modifiedAt":1793960898421,"name":"CNA: redhat","retrievedAt":1793963310226,"url":"https://www.cve.org/CVERecord?id=CVE-2026-107623"},{"modifiedAt":1793963823547,"name":"NVD","retrievedAt":1793967476282,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107623"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793963332706,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107623"}],"ssvc":{"assessedAt":1791481267629,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Keycloak-services: keycloak-services: oidc dcr read-modify-write silently disables offline token revocation","updatedAt":1793967476282}
