Advisory
Source description from Wordfence Intelligence, credited to Ananda Dhakal.
The Easy Digital Downloads – eCommerce Payments and Subscriptions made easy plugin for WordPress is vulnerable to Race Condition in all versions up to, and including, 3.7.1. This is due to a non-atomic check-then-increment pattern in discount usage tracking that allowed concurrent requests to each pass the availability check before either incremented the counter, combined with the absence of per-order claim markers to prevent double-counting. This makes it possible for unauthenticated attackers to apply a limited-use discount code more times than permitted by submitting concurrent checkout requests, bypassing the maximum-use limit. A discount code with a maximum use limit must be configured in the store.
