HIGH EXPLOITED IN THE WILD NUCLEI

WordPress wp-courses <2.0.27 - Auth Bypass

Title source: llm

Exploitation Summary

CVE-2020-26876 has been observed exploited in the wild (reported by VulnCheck KEV, InTheWild.io). A Nuclei detection template is also available.

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).
