Summary
The FAQ Builder AYS WordPress plugin before 1.8.5 does not sanitize or escape content submitted by unauthenticated visitors before storing it and outputting it in an admin area page, and the escaping it does apply is undone by a subsequent decoding step, leading to Stored XSS which will execute in the context of a logged in administrator.
