## Description

The SureCart plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the icon name block attribute in all versions up to, and including, 4.9.6. This is due to the block editor's icon component building a fetch path from the unvalidated icon name and injecting the fetched document's markup into the page, and the server-side SVG loader likewise concatenating the name into a file path. This makes it possible for authenticated attackers with author-level access and above, who can upload a text file containing markup, to point a block's icon at that file and inject arbitrary web scripts that execute when another user, such as an administrator, opens the post in the block editor.
