Chamilo LMS is a learning management system. Prior to 2.0.0-RC.3, an Insecure Direct Object Reference (IDOR) vulnerability in the /social-network/personal-data/{userId} endpoint allows any authenticated user to access full personal data and API tokens of arbitrary users by modifying the userId parameter. This results in mass disclosure of sensitive user information and credentials, enabling a full platform data breach. This vulnerability is fixed in 2.0.0-RC.3.
