Wpfunnels – Funnel Builder For Woocommerce With Checkout & One Click Upsell

The WPFunnels – Easy Funnel Builder To Optimize Buyer Journeys And Get More Leads & Sales plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpf_optin_form' shortcode in all versions up to, and including, 3.7.9 due to insufficient input sanitization and output escaping of the 'button_icon' parameter. 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 WPFunnels – The Easiest Funnel Builder For WordPress And WooCommerce To Collect Leads And Increase Sales plugin for WordPress is vulnerable to unauthorized user registration in all versions up to, and including, 3.6.2. This is due to the plugin relying on a user controlled value 'optin_allow_registration' to determine if user registration is allowed, instead of the site-specific setting. This makes it possible for unauthenticated attackers to register new user accounts, even when user registration is disabled.

The WPFunnels plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the wpfnl_delete_log() function in all versions up to, and including, 3.6.2. This makes it possible for authenticated attackers, with Administrator-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

The Easiest Funnel Builder For WordPress & WooCommerce by WPFunnels plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'post_id' parameter in all versions up to, and including, 3.5.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. This was partially patched in 3.5.4 and fully patched in 3.5.5.
