Common Weakness Enumeration
- CWE-288 - Authentication Bypass Using an Alternate Path or ChannelA product requires authentication, but the product has an alternate path or channel that does not require authentication.
- 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.
