Wordpress Simple Paypal Shopping Cart

The WordPress Simple Shopping Cart plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wp_cart_button' shortcode in all versions up to, and including, 5.1.3 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.

The WordPress Simple Shopping Cart plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.1.3 via the 'process_payment_data' due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to change the quantity of a product to a negative number, which subtracts the product cost from the total order cost. The attack will only work with Manual Checkout mode, as PayPal and Stripe will not process payments for a negative quantity.

The WordPress Simple Shopping Cart plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the automatic redirect URL setting in all versions up to and including 4.7.1 due to insufficient input sanitization and output escaping.

This only affects multi-site installations and installations where unfiltered_html has been disabled.

The WP Simple Shopping Cart plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 4.6.3 due to the plugin saving shopping cart data exports in a publicly accessible location (/wp-content/plugins/wordpress-simple-paypal-shopping-cart/includes/admin/). This makes it possible for unauthenticated attackers to view information that should be limited to administrators only and can include data like first name, last name, email, address, IP Address, and more.

The WordPress Simple Shopping Cart WordPress plugin before 4.6.2 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.
