Common Weakness Enumeration
- CWE-269 - Improper Privilege ManagementThe software does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that 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.
