 "title": "WowStore <= 4.6.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Product Block Attributes",
 "description": "The Store Builder & Product Blocks for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tooltipPosition' and 'className' attributes of its product grid and list blocks in versions 4.0.0 up to, and including, 4.6.0 due to insufficient output escaping. This makes it possible for authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.",
