Security flaw hits popular websites

Security firm Cloudflare disclosed late Thursday that a long-running bug in its security systems may have leaked information, including potentially personal information, from thousands of sites including Uber, Fitbit and OK Cupid. The problem was first uncovered by Google security expert Tavis Ormandy, who let Cloudflare know about the issue on Feb. 18. But the service had been leaking information for months in a way that allowed search engines to pick it up, according to Cloudflare.
