LimeSurvey v5.4.15 was discovered to contain a stored cross-site scripting (XSS) vulnerability in the component /index.php/surveyAdministration/rendersidemenulink?subaction=surveytexts. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Description or Welcome-message text fields. NOTE: the vendor indicates that this is not a vulnerability because the manipulation requires Superadministrator privileges, and Superadministrators are already allowed to customize surveys with JavaScript as they wish.

An arbitrary file upload vulnerability in the plugin manager of LimeSurvey v5.4.15 allows attackers to execute arbitrary code via a crafted PHP file.
