The StoreEngine — Complete eCommerce Solution with Memberships, Licensing, Affiliates & More plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.1.1 via the parse_file_path function. This makes it possible for authenticated attackers, with vendor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
