The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'uacf7_get_generated_pdf' function in all versions up to, and including, 3.5.33. This makes it possible for authenticated attackers, with Subscriber-level access and above, to generate and get form submission PDF, when the "PDF Generator" and the "Database" addons are enabled (disabled by default).
