Summary
The Customer Switching WordPress plugin before 2.1.3 does not securely bind an active user-switching session to the operator who initiated it, allowing a lower-privileged account that an operator is currently switched into to be resolved as that operator and to switch into any permitted account, including an administrator, resulting in full account takeover.
