Movable Type contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate certain unspecified input before being returned to the user. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
