{"id":"CVE-2026-84418","state":"PUBLISHED","title":"DataStage on Cloud Pak for Data Improper Certificate Validation","description":"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.","publishedAt":"2026-10-12T22:25:41.758Z","updatedAt":"2026-10-12T22:53:58.011Z","severity":{"score":7.4,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","source":"ibm"},"assigner":"ibm","products":["IBM DataStage on Cloud Pak for Data"],"affected":[{"vendor":"IBM","product":"DataStage on Cloud Pak for Data","versions":[{"version":"5.4.0.0","status":"affected"}],"cpes":["cpe:2.3:a:ibm:datastage_on_cloud_pak_for_data:5.4.0.0:*:*:*:*:*:*:*"]}],"references":["https://www.ibm.com/support/pages/node/7288649"],"weaknesses":["CWE-295"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/84xxx/CVE-2026-84418.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-84418","state":"PUBLISHED","datePublished":"2026-10-12T22:25:41.758Z","dateUpdated":"2026-10-12T22:53:58.011Z","assignerShortName":"ibm","assignerOrgId":"9a959283-ebb5-44b6-b705-dcc2bbced522","dateReserved":"2026-09-01T17:43:02.446Z"},"containers":{"cna":{"title":"DataStage on Cloud Pak for Data Improper Certificate Validation","descriptions":[{"lang":"en","value":"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.
