The issue occurs when a client specifically requires a higher security level for a user who already has an active session at a lower level. Due to a logic error in how session re-evaluations are handled, Keycloak may incorrectly issue a token at the lower security level instead of enforcing the required higher level, potentially allowing unauthorized access to sensitive resources that rely on these security claims.","state":0,"publishedAt":"2026-09-24T05:47:52.082+00:00","modifiedAt":"2026-09-26T22:51:20.431+00:00","affected":[{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"keycloak-services","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Build of Keycloak\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"keycloak-services\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/a:redhat:build_keycloak:\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"rhbk/keycloak-rhel9","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Build of Keycloak\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"rhbk/keycloak-rhel9\",\n                    \"defaultStatus\": \"affected\",\n                    \"cpes\": [\n                        \"cpe:/a:redhat:build_keycloak:\"\n                    ]\n                }"},{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"keycloak-services","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Red Hat\",\n                    \"product\": \"Red Hat Single Sign-On 7\",\n                    \"collectionURL\": \"https://access.redhat.com/downloads/content/package-browser/\",\n                    \"packageName\": \"keycloak-services\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"cpes\": [\n                        \"cpe:/a:redhat:red_hat_single_sign_on:7\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","score":4.2,"severity":"MEDIUM"}],"references":["https://access.redhat.com/security/cve/CVE-2026-97176","https://bugzilla.redhat.com/show_bug.cgi?id=2539964"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97176","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97176","identifiers":["CVE-2026-97176"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
