MEDIUMCVSS 3.1
EPSS 0.25%
Description
The Big Post Shipping for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wooboigpost_shipping_status' shortcode in all versions up to, and including, 2.1.2 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
