CVE-2018-11564
Estado: ModificadaMedia (4.8)—
Stored XSS in YOOtheme Pagekit 1.0.13 and earlier 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.
