The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via ppress_billing_address Filename Parameter in all versions up to, and including, 4.17.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The vulnerability is exploitable via any page hosting the ProfilePress Tabbed Widget by supplying a malicious filename for the ppress_billing_address file upload field in a crafted POST request.
