Good news, Twitter junkies, it's now safe to return to your normal 140-character microblogging about whatever's on your mind without fear of falling prey to a nasty XSS attack that was running rampant yesterday.
"The exploit is fully patched," Twitter announced in a status update early this morning.
Prior to the patch, a flaw existed that allowed messages to pop-up and third-party websites to open just by moving your cursor over a link. The mischievous mouseover bug was widely being exploited, redirecting visitors of hacked accounts to hardcore porn sites. It was also being used to "auto-tweet" more mouseover links, affecting thousands of Twitter users before Twitter plugged the gaping security hole.
