Official description
Quest Bot is an opensource modern Discord Bot built for moderation, utilities and support. Prior to version 1.0.3, a user with Manage Server / ManageGuild, but without Manage Roles or Administrator, can configure the bot’s AutoRole feature to assign an arbitrary role to new members. If the selected role has Administrator and is below the bot’s highest role, the attacker can join with a controlled account and receive full server admin. This issue has been patched in version 1.0.3.

The underlying weakness: Incorrect Privilege Assignment
A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
