WPC Smart Compare for WooCommerce < 6.4.8 - Authenticated (Contributor+) DOM-Based Stored Cross-Site Scripting

Description

The WPC Smart Compare for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via DOM elements in all versions up to, and including, 6.4.7 due to insufficient input sanitization and 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.
