Who should care

Defenders responsible for WordPress installations, particularly those using Uncanny Toolkit for LearnDash in multisite network environments, should assess exposure and verify the version of the plugin.

Why it matters

Defenders should prioritize verifying the version of Uncanny Toolkit for LearnDash and ensuring it is updated to 3.8.2 or later, particularly in multisite network environments, as the vulnerability allows a subsite administrator to mark arbitrary network users as unverified and prevent them from logging in.

• Account lockout may occur for arbitrary network users outside the site of a subsite administrator
• Verification of Uncanny Toolkit for LearnDash version is required to determine exposure
• Multisite network environments may be particularly vulnerable to exploitation

Technical summary

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. This allows a subsite administrator on a multisite network to mark arbitrary network users outside their own site as unverified, preventing those users from logging in. The vulnerability impacts multisite network environments, particularly those using Uncanny Toolkit for LearnDash. Defenders should prioritize verifying the plugin version and ensuring it is updated to 3.8.2 or later.
