MEDIUM 6.1EPSS 1.23%
Does this matter?
Lower severity and a low EPSS score (1.23%). Track it; it rarely justifies an emergency change on its own.
Description
An XSS vulnerability exists in modules/wysiwyg/save.php of LeptonCMS 4.5.0. This can be exploited because the only security measure used against XSS is the stripping of SCRIPT elements. A malicious actor can use HTML event handlers to run JavaScript instead of using SCRIPT elements.
