The Product Designer App plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.1.3 via the 'svg' parameter parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. The endpoint's only authentication gate relies on a nonce and token that are both publicly emitted as JavaScript globals on any page rendering the [pdapp-studio-page] shortcode, making them freely obtainable by anonymous visitors.
