Tutor LMS SQL Injection and Authorization

SQL injection in Tutor LMS plugin for WordPress through version 3.9.8 allows authenticated Admin-level attackers to extract sensitive database information by injecting malicious SQL via the 'date' parameter, which is insufficiently escaped before being interpolated into a SQL fragment passed to $wpdb->prepare(). The vulnerability requires Admin authentication and does not permit data modification or denial of service. CVSS 6.5 reflects confidentiality impact; exploitation is limited to high-privilege authenticated users.

Tutor LMS plugin for WordPress versions up to 3.9.8 allow authenticated attackers to manipulate course content structure (detach lessons, move lessons between topics, reorder content) without proper authorization checks when the 'content_parent' parameter is omitted from requests to the tutor_update_course_content_order() function. Although the CVSS score of 5.3 reflects the absence of confidentiality impact, the vulnerability enables course instructors or subscribers to disrupt course integrity across the entire site despite lacking content management permissions, with no public exploit code confirmed but patch available in version 3.9.9.
