Common Weakness Enumeration
- CWE-284 - Improper Access ControlThe software does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
- CWE-863 - Incorrect AuthorizationThe software performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions.
