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 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.
