What it is

The Post Status Notifier Lite WordPress plugin before 1.13.0 does not properly escape the `mod` URL parameter before reflecting it into the admin settings page (`admin.php?page=post-status-notifier-lite`), leading to a Reflected Cross-Site Scripting vulnerability that fires in the administrator's session when they are tricked into following a crafted URL.
