CVE-2026-33703
Full vulnerability record from the local CVENow database.
Description
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.

Antes de la versión 2.0.0-RC.3, una vulnerabilidad de Referencia Directa Insegura a Objeto (IDOR) en el endpoint /social-network/personal-data/{userId} permite a cualquier usuario autenticado acceder a datos personales completos y tokens de API de usuarios arbitrarios modificando el parámetro userId. Esto resulta en una divulgación masiva de información sensible del usuario y credenciales, lo que permite una violación de datos completa de la plataforma. Esta vulnerabilidad está corregida en la versión 2.0.0-RC.3."
