The vulnerability arises from a missing authorization check in the save_course_content_order() method, which processes attacker-supplied data without verifying ownership. This can lead to lessons being detached from topics, reordered, or reassigned across courses, compromising the integrity of course materials. The weakness corresponds to CWE\u2011639, where improper checks on user permissions grant unauthorized access to sensitive operations.", "risk_and_exploitability": "The CVSS score of 4.3 indicates a medium severity. Explorability is limited by the requirement of user authentication, but the attacker simply needs to craft an AJAX request with manipulated lesson and topic IDs, a capability available to any subscriber or higher role.

The attack is feasible in typical environments where the plugin is enabled, and it can be exploited by internal users familiar with WordPress AJAX endpoints."}}}}, "created": "2026-04-13T12:41:55.004810+00:00", "updated": "2026-04-13T12:56:38.447763+00:00", "vendors": ["themeum", "themeum$PRODUCT$tutor_lms_\u2013_elearning_and_online_course_solution", "wordpress", "wordpress$PRODUCT$wordpress"]}
