CVE-2026-33736 Details
Description
Chamilo LMS is a learning management system. Prior to 2.0.0-RC.3, any authenticated user (including ROLE_STUDENT) can enumerate all platform users and access personal information (email, phone, roles) via GET /api/users, including administrator accounts. This vulnerability is fixed in 2.0.0-RC.3.
A vulnerability in Chamilo LMS prior to version 2.0.0-RC.3 allows any authenticated user, including those with the ROLE_STUDENT, to enumerate all users on the platform and access personal information such as email addresses, phone numbers, and roles. This includes visibility into administrator accounts. The issue arises because the User API's GetCollection operation is accessible to all users with ROLE_USER, a category that includes all authenticated users. As a result, students can list all users and their details through the API.
Users can upgrade to Chamilo LMS version 2.0.0-RC.3 or later to address this vulnerability.
