Woocommerce Vietnam Checkout < 2.0.8 - Authenticated (Shop manager+) Stored Cross-Site Scripting

Description

The Woocommerce Vietnam Checkout plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the $currency variable in all versions up to, and including, 2.0.7 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.
