Chamilo LMS is a learning management system. Prior to 2.0.0-RC.3, an Insecure Direct Object Reference (IDOR) vulnerability in the REST API stats endpoint allows any authenticated user (including low-privilege students with ROLE_USER) to read any other user's learning progress, certificates, and gradebook scores for any course, without enrollment or supervisory relationship. This vulnerability is fixed in 2.0.0-RC.3.
