Description
Database functions and procedures can be coded using definers rights. This allows anyone who utilizes the object to perform the actions the object allows as if they were the owner. This can lead to privileged actions being taken by unauthorized individuals. If critical tables or other objects rely on unauthorized owner accounts, these objects can be lost when an account is removed. Within the database, object ownership implies full privileges to the owned object including the privilege to assign access to the owned objects to other subjects. Unmanaged or uncontrolled ownership of objects can lead to unauthorized object grants and alterations.
