The FunnelKit - Funnel Builder for WooCommerce Checkout plugin for WordPress is vulnerable to time-based blind SQL Injection via the 'opid' parameter in all versions up to, and including, 3.13.1.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The FunnelKit – Funnel Builder for WooCommerce Checkout plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `wfop_phone` shortcode in all versions up to, and including, 3.13.1.2. This is due to insufficient input sanitization and output escaping on the user-supplied `default` attribute. 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 FunnelKit Automations – Email Marketing Automation and CRM for WordPress & WooCommerce plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.6.4.1. This is due to the plugin not properly verifying that a user is authorized to perform administrative actions in the `bwfan_test_email` AJAX handler. The nonce used for verification is publicly exposed to all visitors (including unauthenticated users) via the frontend JavaScript localization, and the `check_nonce()` function accepts low-privilege authenticated users who possess this nonce. This makes it possible for authenticated attackers, with Subscriber-level access and above, to send arbitrary emails from the site with attacker-controlled subject and body content.
The FunnelKit Automations – Email Marketing Automation and CRM for WordPress & WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.6.4.1 via the '/wc-coupons/' REST API endpoint. This is due to the endpoint being marked as a public API (`public_api = true`), which results in the endpoint being registered with `permission_callback => '__return_true'`, bypassing all authentication and capability checks. This makes it possible for unauthenticated attackers to extract sensitive data including all WooCommerce coupon codes, coupon IDs, and expiration status.
The SlingBlocks – Gutenberg Blocks by FunnelKit (Formerly WooFunnels) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Countdown block's attributes in all versions up to, and including, 1.6.0 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.
Multiple FunnelKit plugins are vulnerable to Sensitive Information Exposure via the wf_get_cookie shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data including authentication cookies of other site users, which may make privilege escalation possible.
Please note both FunnelKit – Funnel Builder for WooCommerce Checkout AND FunnelKit Automations – Email Marketing Automation and CRM for WordPress & WooCommerce are affected by this.
The Bonanza – WooCommerce Free Gifts Lite plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the xlo_optin_call() function in all versions up to, and including, 1.0.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to set the opt in status to success.
The Recover WooCommerce Cart Abandonment, Newsletter, Email Marketing, Marketing Automation By FunnelKit plugin for WordPress is vulnerable to unauthorized arbitrary plugin installation due to a missing capability check on the install_or_activate_addon_plugins() function and a weak nonce hash in all versions up to, and including, 3.5.3. This makes it possible for unauthenticated attackers to install arbitrary plugins on the site that can be leveraged to further infect a vulnerable site.
The Recover WooCommerce Cart Abandonment, Newsletter, Email Marketing, Marketing Automation By FunnelKit plugin for WordPress is vulnerable to SQL Injection via the ‘automationId’ parameter in all versions up to, and including, 3.5.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The SlingBlocks – Gutenberg Blocks by FunnelKit (Formerly WooFunnels) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the "Icon List" Block in all versions up to, and including, 1.5.0 due to insufficient input sanitization and output escaping.

The Funnel Builder for WordPress by FunnelKit – Customize WooCommerce Checkout Pages, Create Sales Funnels, Order Bumps & One Click Upsells plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on multiple functions in all versions up to, and including, 3.4.6. This makes it possible for authenticated attackers, with Contributor-level access and above, to update multiple settings, including templates, designs, checkouts, and other plugin settings.
The Funnel Builder for WordPress by FunnelKit – Customize WooCommerce Checkout Pages, Create Sales Funnels, Order Bumps & One Click Upsells plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘mimes’ parameter in all versions up to, and including, 3.3.1 due to insufficient input sanitization and output escaping.
