Product Variations Swatches for WooCommerce < 1.1.19 - Authenticated (Subscriber+) Stored Cross-Site Scripting

Description

The Product Variations Swatches for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 1.1.18. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
