Frappe LMS vulnerabilities

In Frappe Learning Management System (LMS) versions 2.50.0 and below, a user with course editing role can upload a SCORM ZIP package to write files outside the intended directory. Fixed in version 2.50.1.

Frappe LMS version 2.51.0 and earlier allows users to bypass payment validation for courses by using an unrelated batch. This is fixed in version 2.52.0.

Frappe Learning Management System (LMS) before version 2.46.0 allows students to modify quiz scores before submission. The application relies on client-side calculations that can be altered using browser developer tools, compromising score integrity.

Frappe LMS is vulnerable to stored Cross-Site Scripting (XSS). The vulnerability affects versions from 2.27.0 to before 2.48.0.

Frappe Learning Management System (LMS) prior to version 2.42.0 allowed authenticated attackers to enter JavaScript through the Company Website field of the Job Form, exposing users to an XSS attack. The script could then be executed in the browsers of users who opened the malicious job posting. This issue is fixed in version 2.42.0.

Frappe Learning Management System (LMS) prior to version 2.42.0 allow authenticated users to add malicious HTML and JavaScript through description fields in the Job, Course and Batch forms. This issue is fixed in version 2.42.0.

Frappe Learning Management System (LMS) prior to 2.41.0 has a flaw in server-side authorization logic that allowed authenticated users to perform actions beyond their assigned roles across multiple features. Because affected endpoints relied on client-side or UI-level checks instead of enforcing permissions on the server, users with low-privileged roles (such as students) could perform operations intended only for instructors or administrators via directly using the APIs. This vulnerability is fixed in 2.41.0.
