What is CVE-2026-81210?

IBM DataStage on Cloud Pak for Data version 5.4.0.0 contains a vulnerability that allows unauthorized modification of file paths through concatenation of user-supplied input. This leads to insecure direct object reference (IDOR) and path traversal attacks, enabling attackers to access sensitive files such as job logs and error logs, which may include sensitive connection strings and customer data. As these logs are accessible without proper project access control, this vulnerability represents a risk of leaking critical tenant data across the platform.
