The originally reported vulnerability was based around a specially designed QR code causing Google Glass to connect to a WiFi network not of the owners choosing which would allow monitoring of data flowing to and from the effected Google Glass device.  While this issue was indeed patched there you still need to be aware that connecting to random WiFi can be a big security risk thanks to an unpatched spoofing bug effecting essentially all browsers.  As The Register reminds everyone, unless you are at least encrypting your traffic or using a VPN your data transmission should not be considered secure.
