Sylius is an open source eCommerce platform. In versions prior to 1.9.10, 1.10.11, and 1.11.2, it is possible to upload an SVG file containing cross-site scripting (XSS) code in the admin panel. In order to perform a XSS attack, the file itself has to be open in a new card or loaded outside of the IMG tag. The problem applies both to the files opened on the admin panel and shop pages. The issue is fixed in versions 1.9.10, 1.10.11, and 1.11.2. As a workaround, require a library that adds on-upload file sanitization and overwrite the service before writing the file to the filesystem. The GitHub Security Advisory contains more specific information about the workaround.
The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
