The FireBox – WooCommerce Popup Builder, Exit Intent Popup, Email Optin & Cart Abandonment plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 3.1.10 via the value function. This is due to a trivially bypassable regex blacklist in Executer::allowedToRun() that fails to block WordPress core functions such as wpinsertuser, updateoption, and fileputcontents, combined with no sanitization of PHP condition rule values stored via the fireboxmeta REST endpoint. This makes it possible for authenticated attackers, with author-level access and above, to execute code on the server. On sites upgraded from a version prior to 3.1.10, the Migrator::preserveCampaignRoleAccess() function automatically grants the editfireboxes and publishfireboxes capabilities to the Author role, lowering the effective entry point to Author-level access.

The FireBox Popups – Increase Sales and Grow Your Email List plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.1.7 via the 'formid' parameter. This makes it possible for unauthenticated attackers to extract download a full CSV export of all form submissions — including any personally identifiable information submitted by users — for any arbitrary formid.
