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.","state":0,"publishedAt":"2026-10-12T22:25:41.758+00:00","modifiedAt":"2026-10-12T22:53:58.011+00:00","affected":[{"ecosystem":"Vendor product","name":"DataStage on Cloud Pak for Data","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"IBM\",\n                    \"product\": \"DataStage on Cloud Pak for Data\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"5.4.0.0\"\n                        }\n                    ],\n                    \"cpes\": [\n                        \"cpe:2.3:a:ibm:datastage_on_cloud_pak_for_data:5.4.0.0:*:*:*:*:*:*:*\"\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4,"severity":"HIGH"}],"references":["https://www.ibm.com/support/pages/node/7288649"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-84418","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-84418","identifiers":["CVE-2026-84418"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
