CVE-2026-33706 Details
Description
Chamilo LMS is a learning management system. Prior to 1.11.38, any authenticated user with a REST API key can modify their own status field via the update_user_from_username endpoint. A student (status=5) can change their status to Teacher/CourseManager (status=1), gaining course creation and management privileges. This vulnerability is fixed in 1.11.38.
A privilege escalation vulnerability has been identified in Chamilo LMS versions prior to 1.11.38. This issue allows any authenticated user with a REST API key to modify their own status field using the update_user_from_username endpoint. Specifically, a user with a student status (5) can change their status to Teacher/CourseManager (1), thereby gaining the ability to create and manage courses. The vulnerability arises because the update_user_from_username method does not properly validate status changes, allowing unauthorized modifications of sensitive user fields.
Users can upgrade to Chamilo LMS version 1.11.38 or later to address this vulnerability.
