 "title": "WowStore <= 4.5.8 - Authenticated (Author+) Stored Cross-Site Scripting via SVG File Upload",
 "description": "The product-blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG file uploads in all versions up to, and including, 4.5.8. This is due to the Custom Font add-on adding the SVG MIME type to the allowed upload types for every user who can upload files, without sanitizing the uploaded files. This makes it possible for authenticated attackers, with Author-level access and above, to upload SVG files containing arbitrary web scripts that execute whenever a user accesses the uploaded file.",
