Published: 03 March 2026
Summary
CVE-2025-13687 is a medium-severity OS Command Injection (CWE-78) vulnerability in Ibm Datastage On Cloud Pak For Data. Its CVSS base score is 6.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unix Shell (T1059.004); ranked at the 26.2th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-13687 is an OS command injection vulnerability (CWE-78) in IBM DataStage on Cloud Pak for Data versions 5.1.2 through 5.3.0. It arises from improper validation of user-supplied input in the user-defined function component, which could allow an authenticated user to execute arbitrary commands on the system with normal user privileges. The vulnerability has a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L), indicating medium severity with network accessibility, low attack complexity, and low impacts across confidentiality, integrity, and availability.
An authenticated user with low privileges (PR:L) can exploit this vulnerability remotely over the network without user interaction. By supplying malicious input through the user-defined function component, the attacker can execute arbitrary commands, potentially leading to limited data exposure, modification, or disruption on the affected system, all under the context of normal user privileges.
IBM has published an advisory with remediation details at https://www.ibm.com/support/pages/node/7262347, published on 2026-03-03. Security practitioners should consult this reference for patch availability and mitigation guidance specific to the affected Cloud Pak for Data releases.

Directly requires validation of user-supplied input in the user-defined function component, blocking the OS command injection vector in CVE-2025-13687.
Enforces least privilege so that even a successful injection by an authenticated user is confined to normal (non-elevated) user rights on the DataStage system.
Mandates timely remediation of the identified flaw in IBM DataStage versions 5.1.2–5.3.0, eliminating the command-injection vulnerability.
