Description

WordPress contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate certain input containing protocol strings in the KSES library before use. 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.
