Re: SMF "index.php?action=pm" Cross Site-Scripting
We intend to release a patch for this and a few other reported bugs within the
next day or two (We need to complete testing on it).
Note that this is an extremely difficult exploit to achieve. It requires a user
to follow a link posted by someone else to "Send a PM" with some HTML entities
within the query string and then (I believe) to hit submit at least once. I
would hope that the chances of anyone falling for such a exploit would be
extremely low indeed!
