{"schema":"threatline.record/2","record":{"id":"CVE-2026-97176","aliases":[],"summary":"Keycloak-services: keycloak-services: essential acr requirement silently bypassed via cookie authenticator","details":"A flaw was found in the Level of Authentication enforcement mechanism of Keycloak, an identity and access management solution. 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.","categories":["Identity & access"],"product":"Red Hat Build of Keycloak","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97176","source_modified_at":"2026-09-26T22:51:20.431Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Build of Keycloak","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97176","source_modified_at":"2026-09-26T22:51:20.431Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Build of Keycloak","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97176","source_modified_at":"2026-09-26T22:51:20.431Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Single Sign-On 7","vendor":"Red Hat","versions":[],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":4.2,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00167,"percentile":0.05684,"score_date":"2026-10-23"},"published_at":"2026-09-24T05:47:52.082Z","modified_at":"2026-09-26T22:51:20.431Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97176","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-26T22:51:20.431Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97176","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-97176","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2539964","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-26T22:39:58.730347Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-26T22:51:20.431Z","content_hash":"3ff5e28050edcb072dd734ae78c29477bdceae7061df6bd019a612af56e120d6"}}
