{"schemaVersion":3,"id":"CVE-2026-84418","aliases":[],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-10-12T22:25:41.758Z","modified":"2026-10-12T22:53:58.011Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.4,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.4,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.4,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00136,"percentile":0.02779,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-13T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00136,"percentile":0.02779}],"last30":[{"date":"2026-10-13T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00136,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00136,"percentile":0.02779}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-295","name":"Improper Certificate Validation","description":"The product does not validate, or incorrectly validates, a certificate.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/295.html"}],"affected":[{"vendor":"ibm","product":"datastage on cloud pak for data","name":"DataStage on Cloud Pak for Data","label":"datastage on cloud pak for data","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"5.4.0.0","noFixRecorded":false,"fixedIn":null},{"text":"5.4.0","noFixRecorded":false,"fixedIn":null}],"versionsText":"5.4.0.0 | 5.4.0","eol":null,"hubHref":"/vendor/ibm/datastage_on_cloud_pak_for_data"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://www.ibm.com/support/pages/node/7288649","label":"www.ibm.com/support/pages/node/7288649","hostname":"www.ibm.com","tags":["Vendor Advisory","Patch"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-12T22:25:41.758Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-12T22:53:58.011Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":30,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-22T08:32:03.331Z","stale":false,"partial":false}}
