This is due to a missing authorization check in the tutor_update_course_content_order() function. The function only validates the nonce (CSRF protection) but does not verify whether the user has permission to manage course content. The can_user_manage() authorization check only executes when the 'content_parent' parameter is present in the request. When this parameter is omitted, the function proceeds directly to save_course_content_order() which manipulates the wp_posts table without any authorization validation. This makes it possible for authenticated attackers with subscriber-level access and above to detach all lessons from any topic, move lessons between topics, and modify the menu_order of course content, effectively allowing them to disrupt the structure of any course on the site.","published_at":"2026-04-17T03:36:45.463000Z","last_modified_at":null,"cvss_v3_score":5.3,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-862"],"nvd_references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/f32ae42d-dd1f-41d7-8ae4-ddec56d78ae6?source=cve","https://plugins.trac.wordpress.org/browser/tutor/tags/3.9.7/classes/Course.php#L1700","https://plugins.trac.wordpress.org/browser/tutor/trunk/classes/Course.php#L1789","https://plugins.trac.wordpress.org/browser/tutor/tags/3.9.7/classes/Course.php#L1789","https://plugins.trac.wordpress.org/browser/tutor/trunk/classes/Course.php#L1700","https://plugins.trac.wordpress.org/changeset/3505142/tutor/tags/3.9.9/classes/Course.php"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:55.040689Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"themeum","vendor_name":"themeum","product_slug":"tutor-lms-elearning-and-online-course-solution","product_name":"Tutor LMS – eLearning and online course solution","version_start":"0","version_start_inclusive":true,"version_end":"3.9.8","version_end_inclusive":true,"cpe23_uri":"cve5:themeum:tutor-lms-elearning-and-online-course-solution:0:3.9.8"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f32ae42d-dd1f-41d7-8ae4-ddec56d78ae6?source=cve","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/3.9.7/classes/Course.php#L1700","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/trunk/classes/Course.php#L1789","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/3.9.7/classes/Course.php#L1789","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/trunk/classes/Course.php#L1700","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3505142/tutor/tags/3.9.9/classes/Course.php","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-04-17T03:36:45.463000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:48.239489Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:48.239489Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:48.239489Z","label":"CVSS score revised","source":"cvelistv5"}]}
