{"id":"CVE-2026-4484","state":"PUBLISHED","title":"Masteriyo LMS <= 2.1.6 - Missing Authorization to Authenticated (Student+) Privilege Escalation to Administrator","description":"The Masteriyo LMS plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.1.6. This is due to the plugin allowing a user to update the user role through the 'InstructorsController::prepare_object_for_database' function. This makes it possible for authenticated attackers, with Student-level access and above, to elevate their privileges to that of an administrator.","publishedAt":"2026-03-26T01:25:33.967Z","updatedAt":"2026-04-08T16:42:43.176Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["masteriyo Masteriyo LMS – Online Course Builder for eLearning, LMS & Education"],"affected":[{"vendor":"masteriyo","product":"Masteriyo LMS – Online Course Builder for eLearning, LMS & Education","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.1.6","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/265be0af-66a4-4636-ab81-f8e2c5a1282e?source=cve","https://plugins.trac.wordpress.org/browser/learning-management-system/tags/2.1.6/includes/RestApi/Controllers/Version1/InstructorsController.php#L305","https://plugins.trac.wordpress.org/changeset/3490792/learning-management-system/trunk/includes/RestApi/Controllers/Version1/InstructorsController.php"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4484.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4484","state":"PUBLISHED","datePublished":"2026-03-26T01:25:33.967Z","dateUpdated":"2026-04-08T16:42:43.176Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-20T07:04:46.566Z"},"containers":{"cna":{"title":"Masteriyo LMS <= 2.1.6 - Missing Authorization to Authenticated (Student+) Privilege Escalation to Administrator","descriptions":[{"lang":"en","value":"The Masteriyo LMS plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.1.6.
