The Where Did You Hear About Us Checkout Field for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via order meta in all versions up to, and including, 1.3.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with shop manager-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Storefront Footer Text WordPress plugin through 1.0.1 does not sanitize and escape the "Footer Credit Text" added to pages, allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered-html capability is disallowed.
