 "title": "MarketKing — Ultimate WooCommerce Multivendor Marketplace Solution <= 2.1.72 - Authenticated (Vendor+) Stored Cross-Site Scripting via Excessive Vendor Capabilities",
 "description": "The MarketKing plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.1.72. This is due to the vendor_upload_items 'user_has_cap' filter giving every vendor broad WordPress capabilities, including unfiltered_html, edit_posts, publish_posts, edit_published_posts, moderate_comments, manage_categories and edit_shop_orders. This makes it possible for authenticated attackers with vendor-level access to create and publish posts containing arbitrary web scripts, which run whenever a user, including an administrator, views an injected page.",
