Prior to 1.11.38 and 2.0.0-RC.3, Chamilo LMS contains an Insecure Direct Object Reference (IDOR) vulnerability in the Learning Path progress saving endpoint.

Any authenticated user enrolled in a course can overwrite another user's Learning Path progress by simply changing the uid parameter in the request.
