{"id":"CVE-2026-5502","state":"PUBLISHED","title":"Tutor LMS <= 3.9.8 - Authenticated (Subscriber+) Arbitrary Course Content Manipulation via tutor_update_course_content_order","description":"The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized course content manipulation in versions up to and including 3.9.8. 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.","publishedAt":"2026-04-17T03:36:45.463Z","updatedAt":"2026-04-17T14:28:01.492Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["themeum Tutor LMS – eLearning and online course solution"],"affected":[{"vendor":"themeum","product":"Tutor LMS – eLearning and online course solution","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.9.8","versionType":"semver"}]}],"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"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/5xxx/CVE-2026-5502.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-5502","state":"PUBLISHED","datePublished":"2026-04-17T03:36:45.463Z","dateUpdated":"2026-04-17T14:28:01.492Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-03T15:48:58.659Z"},"containers":{"cna":{"title":"Tutor LMS <= 3.9.8 - Authenticated (Subscriber+) Arbitrary Course Content Manipulation via tutor_update_course_content_order","descriptions":[{"lang":"en","value":"The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to unauthorized course content manipulation in versions up to and including 3.9.8.
