The datawould only be accessible to the new windowfor a very brief period, but the result is that itcould be possible for a malicious web siteoperator to view files on the computer ofa visiting user. The web site operator would need toknow (or guess) the name and location of thefile, and could only view file types thatcan be opened in a browser window.
