A stored cross-site scripting (XSS) vulnerability in the Public Survey function of Vanderbilt REDCap 13.1.9 allows authenticated users to execute arbitrary web scripts or HTML via injecting a crafted payload into the 'Survey Title' and 'Survey Instructions' fields. This vulnerability could be exploited by attackers to execute malicious scripts when the survey is accessed through its public link. It is advised to update to version 14.2.1 or later to fix this issue.
