CVE-2026-92715 · Severity: medium · CVSS 4.3 · Published 2026-10-17

Tutor LMS is a WordPress plugin for managing online courses and educational content. Authenticated users with author-level access can modify or steal courses created by other instructors by directly manipulating course IDs, allowing them to overwrite course content and reassign ownership. This could result in loss of course integrity, theft of intellectual property, and disruption of online learning platforms.

## Technical details

The plugin fails to validate the 'ID' parameter in course update requests, allowing authenticated attackers to bypass authorization checks through insecure direct object reference (IDOR). The vulnerability exists because Input::sanitize_array() preserves attacker-controlled POST keys including 'ID' without validation, and WordPress's wp_insert_post() interprets a supplied ID as an update operation on an existing post rather than creation of a new one. An attacker with author-level access can exploit this to modify or claim ownership of any course.
