Product Labels For Woocommerce < 1.5.4 - Authenticated (Shop manager+) Stored Cross-Site Scripting

Description The Product Labels For Woocommerce (Sale Badges) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘‘badgeLabel’ parameter in all versions up to, and including, 1.5.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with shop manager-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
