Uncanny Toolkit for LearnDash < 3.8.2 - Admin+ Cross-Site Account Lockout via Missing Authorization

The Uncanny Toolkit for LearnDash WordPress plugin before 3.8.2 does not verify that the acting user is permitted to manage the targeted accounts before changing their verification state, allowing a subsite administrator on a multisite network to mark arbitrary network users outside their own site as unverified and prevent those users from logging in.
