{"schema":"threatline.record/2","record":{"id":"CVE-2026-84418","aliases":[],"summary":"DataStage on Cloud Pak for Data Improper Certificate Validation","details":"IBM DataStage on Cloud Pak for Data 5.4.0.0 can allow a man-in-the-middle attacker to present a forged TLS certificate, intercept the connection, and capture the IAM bearer Authorization header automatically attached by the session adapter. The captured token grants full platform-scope tenant API access, enabling the attacker to read and manipulate the victim's DataStage projects, flows, assets, and pipeline definitions. This is client-side SDK code running on the user's own machine, so exploitation requires an external network interceptor rather than a co-tenant in the shared cluster.","categories":["Unclassified"],"product":"DataStage on Cloud Pak for Data","vendor":"IBM","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-84418","source_modified_at":"2026-10-12T22:53:58.011Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"DataStage on Cloud Pak for Data","vendor":"IBM","versions":[{"status":"affected","version":"5.4.0.0"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.4,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00136,"percentile":0.02792,"score_date":"2026-10-23"},"published_at":"2026-10-12T22:25:41.758Z","modified_at":"2026-10-12T22:53:58.011Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-84418","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-12T22:53:58.011Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-84418","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.ibm.com/support/pages/node/7288649","tags":["vendor-advisory","patch"]}],"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":"2026-10-12T22:44:08.758443Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-12T22:53:58.011Z","content_hash":"019227f575a21b40eea95efc83ed99382e3454f345add3b370131616544c56ab"}}
