WP Forms Signature Contract Add-On < 1.8.3 - Missing Authorization to Authenticated (Subscriber+) Notice Dimissal

Description

The WP Forms Signature Contract Add-On plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 1.8.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to dismiss notices.
