{"id":"CVE-2026-93882","published":"2026-10-01T08:16:53.330","lastModified":"2026-10-03T16:16:44.493","description":"The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 4.4.8 via the CourseMaterialTemplate::render_material_items() callback exposed on the public lp-ajax-handle (load_content_via_ajax) endpoint. The endpoint is explicitly listed in the AbstractAjax no-nonce allowlist and performs no capability check, and the render_material_items() handler decides authorization against one attacker-supplied identifier (course_id) while fetching the returned material rows via a second, independently attacker-supplied identifier (item_id) with no check that the lesson belongs to the authorized course. This makes it possible for unauthenticated attackers to read and download course-material files (uploaded and external file paths/URLs) belonging to lessons in paid or enrollment-required courses, provided any single course on the site has 'No Required Enroll' enabled and owns at least one material file.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/learnpress/tags/4.4.7/inc/Ajax/AbstractAjax.php#L31","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/learnpress/tags/4.4.7/inc/Ajax/LoadContentViaAjax.php#L25","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/learnpress/tags/4.4.7/inc/Databases/class-lp-material-db.php#L92","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/learnpress/tags/4.4.7/inc/TemplateHooks/Course/CourseMaterialTemplate.php#L113","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/learnpress/tags/4.4.7/inc/TemplateHooks/Course/CourseMaterialTemplate.php#L143","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/1f35f646-1bd6-4785-bdc2-c815644b2b2d?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The LearnPress WordPress plugin has an insecure direct object reference vulnerability that allows unauthenticated attackers to access course materials from paid or enrollment-required courses by exploiting a public AJAX endpoint. This occurs because the system uses two separate identifiers for authorization and data retrieval without properly validating that the lesson belongs to the authorized course.","exploitability":"The vulnerability is easily exploitable with no prerequisites as attackers can directly call the public lp-ajax-handle endpoint with any course_id and item_id parameters to access unauthorized course materials.","blast_radius":"An attacker could potentially access all course material files from any paid or enrollment-required course on the site, including uploaded files and external URLs, if at least one course has 'No Required Enroll' enabled.","remediation":"Upgrade to LearnPress version 4.4.9 or later to fix this vulnerability.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["lms","wp-plugin","access-control","file-access"],"model":"garnet-coder","analyzedAt":"2026-10-13T09:06:03.787Z"}}
