While iOS 7 has provided a lot of bug fixes for Apple users, it has also opened one new exploit that Apple is quickly working to patch.
The iOS 7 bug involves entering a series of taps and presses on the lock screen (video below). This is rather involved and difficult, but once done, it allows access to the images stored in Camera Roll, as well as all the apps that are used for sharing those images, such as Twitter.
An Apple spokesperson told AllThingsD that the company is "aware" of the issue and will deliver a fix soon.
Until an official fix is available from Apple, iOS 7 users can set up a temporary stop gap by disabling access to the Control Center on the lock screen. From Settings, go to Control Center. From here, swipe the option on Access on Lock Screen so that it no longer displays on the lock screen.
