Hustle – Email Marketing, Lead Generation, Optins, Popups <= 7.8.5 - Missing Authorization to Unauthorized Form Submission

The Hustle – Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to unauthorized form submissions due to a missing capability check on the submit_form() function in all versions up to, and including, 7.8.5. This makes it possible for unauthenticated attackers to submit unpublished forms.
