## Affected

- Unknown FooSales: fixed in 1.43.3

## Description

The FooSales WordPress plugin before 1.43.3 does not verify that an authenticated caller is entitled to act as the user a request names, allowing any authenticated user to have the FooSales WordPress plugin before 1.43.3 act as an arbitrary other user, including an administrator, resulting in that user's account details being exposed and their account being taken over.
