## Description

The LifterLMS plugin for WordPress is vulnerable to an access restriction bypass via the checkout handlers in all versions up to, and including, 10.3.0, due to the purchasability check not verifying that the submitted access plan is published. Deleting an access plan only moves it to the trash. This makes it possible for unauthenticated attackers to check out with a deleted (trashed) access plan by submitting its ID, for example to enroll in a course or membership at the price or free terms of a plan the site owner removed.
