Summary
The ThemeMakers PayPal Express Checkout plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'paypal' shortcode in versions up to, and including, 1.1.9 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
