NotificationX <= 3.1.11 - Missing Authorization to Authenticated (Contributor+) Analytics Reset

The NotificationX plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'regenerate' and 'reset' REST API endpoints in all versions up to, and including, 3.1.11. This makes it possible for authenticated attackers, with Contributor-level access and above, to reset analytics for any NotificationX campaign, regardless of ownership.
