## Description

AccessAlly WordPress plugin versions prior to 3.3.2 contain an unauthenticated arbitrary PHP code execution vulnerability in the Login Widget. The plugin processes the login_error parameter as PHP code, allowing an attacker to supply and execute arbitrary PHP in the context of the WordPress web server process, resulting in remote code execution.
