## Technical details

A stored cross-site scripting (XSS) vulnerability exists in IBM watsonx.data intelligence versions 5.2.0 through 5.3.0. The flaw is caused by improper neutralization of user-supplied input during web page generation (CWE-79). An authenticated attacker with low privileges can inject arbitrary JavaScript into the Web UI. When other users view the affected page, the script executes in their browser context, potentially allowing the attacker to disclose session credentials or perform actions on behalf of the victim. The issue is addressed in version 5.3.1.
