CVE-2018-18943
In the Register New Category feature of the Upload menu, the category name can be used for XSS via the data[UploaderCategory][name] parameter to an admin/uploader/uploader_categories/edit URI.
Does this matter?
Lower severity and a low EPSS score (0.73%). Track it; it rarely justifies an emergency change on its own.
