Vulnerability Overview

The Quiz And Survey Master plugin for WordPress is vulnerable to exessive quiz attempts due to a missing validation checks on the ajax_submit_results() function in versions up to, and including, 8.1.10. This makes it possible for unauthenticated attackers to bypass the set limits for the number of times a user can attempt a quiz.

How does WordSec protect against this?

The fix is the thing that ends this: Quiz and Survey Master (QSM) 8.1.11 closes this, and updating the plugin is the step that ends it.
