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.","cvssScore":7.4,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-295"],"vendors":["ibm"],"products":["datastage on cloud pak for data"],"references":[{"url":"https://www.ibm.com/support/pages/node/7288649","tags":["Patch","Vendor Advisory"]}],"exploitRefs":[],"hasPoc":false,"ai":null}
