Official 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.
