CVE-2018-11564: Cross-site Scripting

June 2, 2018 (updated July 5, 2018)

A Stored XSS in YOOtheme Pagekit allows a user to upload malicious code via the picture upload feature. A user with elevated privileges could upload a photo to the system in an SVG format. This file will be uploaded to the system and it will not be stripped or filtered. The user can create a link on the website pointing to /storage/poc.svg that will point to http://localhost/pagekit/storage/poc.svg. When a user comes along to click that link, it will trigger a XSS attack.
