{"schema":"threatline.record/2","record":{"id":"CVE-2026-105305","aliases":[],"summary":"Keycloak-services: keycloak-services: device authorization grant bypasses per-client minimum.acr.value enforcement","details":"A flaw was found in the OIDC implementation of Keycloak, specifically within the Device Authorization Grant flow. This component allows devices with limited input capabilities to obtain security tokens. The issue occurs because the flow fails to check the minimum authentication level required by a client configuration. This allows an attacker who has stolen a user's password to bypass mandatory multi-factor authentication and gain unauthorized access to the Keycloak Admin REST API.","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-2026-105305","source_modified_at":"2026-10-06T12:44:17.153Z","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-2026-105305","source_modified_at":"2026-10-06T12:44:17.153Z","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-2026-105305","source_modified_at":"2026-10-06T12:44:17.153Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Single Sign-On 7","vendor":"Red Hat","versions":[],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":5.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00189,"percentile":0.08062,"score_date":"2026-10-23"},"published_at":"2026-10-06T07:33:32.777Z","modified_at":"2026-10-06T12:44:17.153Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-105305","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-06T12:44:17.153Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-105305","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-2026-105305","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2545801","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":"2026-10-06T12:44:09.472814Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-06T12:44:17.153Z","content_hash":"26210d337d09fa8d81905908fb98dbc34b8bf931e9599172b0e0b80fce0b97a5"}}
