Re: XMLHttpRequest file upload vulnerability Chrome 2 & Safari 3

.html can be crafted to force a unaware user to read file from local, and then possibly send it to a server.

particular browser; it is also fairly well-known and documented; see:
(multiple sections discussing file: access rules, including
XMLHttpRequest, DOM access, etc)
