Advisory
Source description from Wordfence Intelligence, credited to Phil Wylie (mustardbees).
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.
