- **CVSS Score:** 7.7 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N)
- **CWE:** CWE-639
- **Published:** Sep 10, 2026

## 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.

## Affected Products

- IBM — DataStage on Cloud Pak for Data (5.4.0.0)
