Description
The WP Import Export Lite WordPress plugin before 3.9.33 does not escape custom field names retrieved from the database before inserting them into the DOM of one of its administration screens, allowing users with a role as low as contributor to perform Stored XSS attacks which will trigger in the browser of a high privileged user, such as an administrator, viewing that screen.
A stored cross-site scripting vulnerability has been identified in the WP Import Export Lite WordPress plugin, affecting versions prior to 3.9.33.
