Advanced Woo Labels < 2.49 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'bg_color' Parameter

Description

The Advanced Woo Labels – Product Labels & Badges for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'bg_color' parameter in all versions up to, and including, 2.48 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.
