This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The route's permission callback only verifies a generic wp_rest nonce that the plugin itself emits inside the public acadlixOptions JavaScript object on every frontend page, effectively reducing the authentication requirement to unauthenticated."}],"title":"Acadlix LMS <= 1.1.9 - Unauthenticated Arbitrary File Deletion via 'delete_file_data.file_path' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/b54682f6-914e-4c16-b8fb-63b5dcb14933?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/acadlix/tags/1.1.8/includes/Common/REST/Front/FrontQuizController.php#L692"},{"url":"https://plugins.trac.wordpress.org/browser/acadlix/tags/1.1.8/includes/Common/REST/Front/FrontQuizController.php#L680"},{"url":"https://plugins.trac.wordpress.org/browser/acadlix/tags/1.1.8/includes/Common/REST/Front/FrontQuizController.php#L807"},{"url":"https://plugins.trac.wordpress.org/browser/acadlix/tags/1.1.8/includes/Common/Assets/Manager.php#L570"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-22 Improper Limitation of a Pathname to a Restricted Directory","cweId":"CWE-22","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","baseScore":9.1,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"antaloaalonso"}],"timeline":[{"time":"2026-10-01T14:41:29.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-30T20:09:07.000Z","lang":"en","value":"Disclosed"}]}}}
