IBM DataStage on Cloud Pak for Data Has Critical Remote Info Leak

IBM DataStage on Cloud Pak for Data version 5.4.0.0 contains a critical security vulnerability that allows remote authenticated attackers to access sensitive information. The flaw, identified as CVE-2026-82103, was recorded in the National Vulnerability Database with a CVSS score of 9.6. This high severity rating indicates that the issue poses a significant risk to organizations using this specific software configuration.

The vulnerability stems from an exposure of sensitive information to an unauthorized actor. According to the NVD record, the weakness is classified under CWE-200. This means that the application fails to restrict access to sensitive data properly. A remote attacker who has already authenticated to the system can exploit this misconfiguration. They can then obtain information that should remain protected from unauthorized users.

Context and Background

The National Vulnerability Database lists CVE-2026-82103 as a critical issue. The CVSS score of 9.6 places it in the highest severity range. The weakness is categorized as CWE-200, which refers to information exposure. This type of vulnerability occurs when software discloses sensitive data to actors outside the intended security boundary. In this case, the data is exposed to an unauthorized actor. The exposure happens within the IBM DataStage component of Cloud Pak for Data.

The flaw allows remote authenticated attackers to obtain sensitive information. This means that any user with login access could potentially exploit the issue. The impact is limited to information disclosure. The attacker can view data that they should not have access to. The severity depends on the sensitivity of the data stored in the system. Organizations must verify their version to determine if they are impacted.
