CVE-2026-81210

DataStage on Cloud Pak for Data has several vulnerabilities due to open source software

Published Sep 10, 2026 CVSS 3.1 · 7.7 High EPSS < 1% KEV · Not listed
Description
IBM DataStage on Cloud Pak for Data 5.4.0.0 concatenates three caller-supplied strings into a String.format path on the shared /ds-storage RWX PVC and returns the file with no project ACL — pure IDOR plus traversal. Read is constrained to files named job.log/error.log, but DataStage job logs routinely carry connection strings, {dsnextenc} ciphertexts (decryptable via d2-f023), and customer-data row samples. This is the operator's tenant-to-tenant PVC-leakage threat verbatim; MEDIUM→HIGH via threat match.
