Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 10.6%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
Description
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).
