{"schema":"threatline.record/2","record":{"id":"CVE-2026-97846","aliases":[],"summary":"Keycloak-services: keycloak-services: standard token exchange v2 bypasses mtls holder-of-key binding","details":"Keycloak provides a feature called mTLS holder-of-key binding which ensures that a token can only be used by the client that originally requested it by binding it to their digital certificate. A flaw was discovered where the new Standard Token Exchange V2 feature does not check for this certificate. This allows an attacker with stolen client credentials to obtain a standard, unrestricted token that bypasses these security protections.","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-2026-97846","source_modified_at":"2026-09-25T13:53:07.688Z","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-2026-97846","source_modified_at":"2026-09-25T13:53:07.688Z","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-2026-97846","source_modified_at":"2026-09-25T13:53:07.688Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Single Sign-On 7","vendor":"Red Hat","versions":[],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00135,"percentile":0.0269,"score_date":"2026-10-23"},"published_at":"2026-09-25T06:16:38.415Z","modified_at":"2026-09-25T13:53:07.688Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97846","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-25T13:53:07.688Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97846","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-2026-97846","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2540949","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":"total","assessed_at":"2026-09-25T13:52:32.447170Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-25T13:53:07.688Z","content_hash":"d1685b7745049ba1e26c460296813ef6351d06efed8c8f6b9992b43fef56ad97"}}
