Input validation vulnerability in EasyEvent 1.0.0

The EasyEvent plugin for WordPress has a security issue that allows hackers to inject harmful web scripts through the admin settings. This can happen in any version up to 1.0.0 because the plugin does not properly clean the input and output. If an attacker has administrator-level access, they can add these scripts to pages and whenever a user visits those pages, the scripts will run. This only affects websites with multiple installations or with a specific security setting disabled.
