Name of the Vulnerable Software and Affected Versions LimeSurvey version 3.21.1

Description The issue concerns cross-site scripting (XSS) in the Add Participants Function, specifically affecting the First and last name parameters. When a survey participant is being edited, for instance by an administrative user, the JavaScript code will be executed in the browser.

Recommendations For LimeSurvey version 3.21.1, as a temporary workaround, consider restricting access to the Add Participants Function to minimize the risk of exploitation.
