{"id":"CVE-2026-93779","published":"2026-11-07T05:19:02.860","lastModified":"2026-11-08T19:17:43.610","description":"The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.2 via the init_routes due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to read paid course lesson and topic content without enrollment, retrieve quiz answer keys including the is_correct field before attempting a quiz, and enumerate the email addresses, usernames, and registration data of other users including instructors and administrators. Exploitation requires that the attacker hold a valid Tutor LMS API key/secret pair, which is issued to subscriber-level users through the plugin's API key management feature.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.9/classes/RestAPI.php#L135","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.9/classes/RestAPI.php#L376","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.9/classes/RestAPI.php#L418","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.9/classes/RestAPI.php#L460","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.9/restapi/REST_Author.php#L43","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.9/restapi/REST_Course.php#L303","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.9/restapi/REST_Quiz.php#L209","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/tutor/tags/4.0.9/restapi/RestAuth.php#L331","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3748228%40tutor&new=3748228%40tutor","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b0c8b586-784e-43a4-8bb8-c7cb771476a4?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
