The Abandoned Cart Pro for WooCommerce plugin contains an authenticated arbitrary file upload vulnerability due to missing file type validation in the wcap_add_to_cart_popup_upload_files function in all versions up to, and including, 9.16.0. This makes it possible for an authenticated attacker, with subscriber-level access and above, to upload arbitrary files on the affected site's server which may allow for either remote or local code execution depending on the server configuration.
The Abandoned Cart Lite for WooCommerce and Abandoned Cart Pro for WooCommerce plugins for WordPress are vulnerable to Stored Cross-Site Scripting via multiple parameters in versions up to, and including, 5.1.3 and 7.12.0 respectively, due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in user input that will execute on the admin dashboard.
