Description
The Checkout for PayPal plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcodes ('item_description' and 'amount') within the ‘checkout_for_paypal_button_handler’ function in versions up to, and including, 1.0.13 due to insufficient input sanitization and output escaping. This makes it possible for contributor-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
