Technical details
A stored cross-site scripting (XSS) vulnerability exists in the Cognos Administration component of IBM Cognos Analytics and Cognos Transformer. The flaw allows a remote authenticated user with certain privileges to inject malicious JavaScript code into the application's web interface. Because the script is stored, it executes in the context of any user who subsequently views the affected page. This can lead to the disclosure of sensitive information, such as session credentials, or the alteration of intended web functionality. The vulnerability is tracked as CVE-2025-36126 and has a CVSS base score of 6.4.
