{"schema":"threatline.record/2","record":{"id":"CVE-2026-105302","aliases":[],"summary":"Keycloak-services: keycloak-services: user session note mapper exposes upstream idp access tokens","details":"A flaw was found in the User Session Note mapper of the Keycloak identity and access management solution. The issue occurs because the mapper does not validate whether a requested session note contains sensitive internal credentials, such as federated access tokens from external identity providers. This allows a delegated client administrator to leak a user's upstream bearer tokens into the tokens issued to their managed application, potentially leading to unauthorized access to the user's data on external platforms.","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-2026-105302","source_modified_at":"2026-10-05T14:55:01.489Z","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-2026-105302","source_modified_at":"2026-10-05T14:55:01.489Z","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-2026-105302","source_modified_at":"2026-10-05T14:55:01.489Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Single Sign-On 7","vendor":"Red Hat","versions":[],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":5.7,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00201,"percentile":0.09513,"score_date":"2026-10-23"},"published_at":"2026-10-05T05:51:58.125Z","modified_at":"2026-10-05T14:55:01.489Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-105302","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T14:55:01.489Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-105302","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-2026-105302","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2545800","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":"2026-10-05T13:06:52.352902Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-05T14:55:01.489Z","content_hash":"28e1a128c59badd0e8f89b56f3af958a7c1f3881db649a4593702d921efdfe22"}}
