Moodle LMS 4.0 contains a cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious scripts by submitting payloads through the search parameter. Attackers can inject JavaScript code via the search field in course/search.php to execute arbitrary scripts in users' browsers and steal session cookies.

A flaw was found in Moodle. A remote code execution risk was identified in the Moodle LMS Dropbox repository. By default, this was only available to teachers and managers on sites with the Dropbox repository enabled.
