{"id":"CVE-2025-11923","state":"PUBLISHED","title":"LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes - Various Versions - Authenticated (Student+) Privilege Escalation","description":"The LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes plugin for WordPress is vulnerable to privilege escalation. This is due to the plugin not properly validating a user's identity prior to allowing them to modify their own role via the REST API. The permission check in the update_item_permissions_check() function returns true when a user updates their own account without verifying the role changes. This makes it possible for authenticated attackers, with student-level access and above, to escalate their privileges to administrator by updating their own roles array via a crafted REST API request. Another endpoint intended for instructors also provides an attack vector. Affected version ranges are 3.5.3-3.41.2, 4.0.0-4.21.3, 5.0.0-5.10.0, 6.0.0-6.11.0, 7.0.0-7.8.7, 8.0.0-8.0.7, 9.0.0-9.0.7, 9.1.0.","publishedAt":"2025-11-13T03:27:39.431Z","updatedAt":"2025-11-13T14:34:06.521Z","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":["chrisbadgett LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes"],"affected":[{"vendor":"chrisbadgett","product":"LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes","defaultStatus":"unaffected","versions":[{"version":"3.5.3","status":"affected","lessThanOrEqual":"3.41.1","versionType":"semver"},{"version":"4.0.0","status":"affected","lessThanOrEqual":"4.21.3","versionType":"semver"},{"version":"5.0.0","status":"affected","lessThanOrEqual":"5.10.0","versionType":"semver"},{"version":"6.0.0","status":"affected","lessThanOrEqual":"6.11.0","versionType":"semver"},{"version":"7.0.0","status":"affected","lessThanOrEqual":"7.8.7","versionType":"semver"},{"version":"8.0.0","status":"affected","lessThanOrEqual":"8.0.7","versionType":"semver"},{"version":"9.0.0","status":"affected","lessThanOrEqual":"9.0.7","versionType":"semver"},{"version":"9.1.0","status":"affected"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/cc13d13c-6b79-4bf1-8e77-c8cb836dc0c5?source=cve","https://plugins.trac.wordpress.org/browser/lifterlms/trunk/libraries/lifterlms-rest/includes/server/class-llms-rest-students-controller.php#L386","https://plugins.trac.wordpress.org/browser/lifterlms/trunk/libraries/lifterlms-rest/includes/abstracts/class-llms-rest-users-controller.php#L721","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3393703%40lifterlms%2Ftrunk&old=3388956%40lifterlms%2Ftrunk&sfp_email=&sfph_mail="],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/11xxx/CVE-2025-11923.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-11923","state":"PUBLISHED","datePublished":"2025-11-13T03:27:39.431Z","dateUpdated":"2025-11-13T14:34:06.521Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-10-17T18:50:39.481Z"},"containers":{"cna":{"title":"LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes - Various Versions - Authenticated (Student+) Privilege Escalation","descriptions":[{"lang":"en","value":"The LifterLMS – WP LMS for eLearning, Online Courses, & Quizzes plugin for WordPress is vulnerable to privilege escalation.
