Description

Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to version 2.52.0, an authenticated user with a course editing role can inject malicious JavaScript through meta tag fields in the Course Management module. The values are stored without adequate HTML sanitization and are not safely escaped when rendered, allowing stored cross-site scripting. This issue is fixed in version 2.52.0.
