## Technical details

IBM watsonx.data intelligence versions 5.2.0 through 5.3.0 are vulnerable to cross-site scripting (XSS) due to improper neutralization of user-supplied input during web page generation (CWE-79). An authenticated attacker can inject arbitrary JavaScript code into the Web UI. If a victim views the affected page, the script executes within the context of their browser session, potentially allowing the attacker to disclose sensitive information such as session credentials or alter application functionality. The vulnerability is addressed in version 5.3.1.
