Vulnerability Overview

The wp-courses plugin through 2.0.27 for WordPress allows remote attackers to bypass the intended payment step (for course videos and materials) by using the /wp-json REST API, as exploited in the wild in September 2020. This occurs because show_in_rest is enabled for custom post types (e.g., /wp-json/wp/v2/course and /wp-json/wp/v2/lesson exist).

Technical Analysis

REMEDIATION: Update to version 2.0.29, or a newer patched version --- IDENTIFIER: CWE-284 (Improper Access Control) The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
