CVE-2026-35610

Full vulnerability record from the local CVENow database.

Description

PolarLearn is a free and open-source learning program. In 0-PRERELEASE-14 and earlier, setCustomPassword(userId, password) and deleteUser(userId) in the account-management module used an inverted admin check. Because of the inverted condition, authenticated non-admin users were allowed to execute both actions, while real admins were rejected. This is a direct privilege-escalation issue in the application.

En 0-PRERELEASE-14 y versiones anteriores, setCustomPassword(userId, password) y deleteUser(userId) en el módulo de gestión de cuentas utilizaban una comprobación de administrador invertida. Debido a la condición invertida, a los usuarios autenticados no administradores se les permitía ejecutar ambas acciones, mientras que los administradores reales eran rechazados. Esto es un problema directo de escalada de privilegios en la aplicación."
