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.","published":"2026-10-12T23:17:45.000Z","lastModified":"2026-10-14T23:50:00.000Z","status":"Analyzed","sourceIdentifier":"psirt@us.ibm.com","cvss":{"version":"3.1","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"},"cwe":["CWE-295"],"affected":["ibm/datastage on cloud pak for data"],"epss":{"score":0.00136,"percentile":0.03041,"date":"2026-10-27","history":[{"date":"2026-10-13","score":0.00136,"percentile":0.02678}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.14%).
