This allows attackers to bypass intended access restrictions.","Assuming a user with a given identity, authorization is the process of determining whether that user can access a given resource, based on the user's privileges and any permissions or other access-control specifications that apply to the resource.\nWhen access control checks are incorrectly applied, users are able to access data or perform actions that they should not be allowed to perform.
