Description

The WP Post Author WordPress plugin versions before 4.2.0 contain a missing authorization vulnerability. This flaw allows unauthenticated users to overwrite the display name, nickname, and website of the first user account, typically the administrator, during front-end registration if the registration form includes those fields. The issue is fixed in version 4.2.0.
