The iPhone lockscreen bypass bug that was reported by a security researcher, Jose Rodriguez has gone unpatched as Apple is prepping to release the newest version of its mobile OS next week.
While the exploit allow just anyone to bypass the iPhone lockscreen to gain access to contact information, and perhaps other piece of information saved on the device. The bug was first spotted in 2018 on iOS 12.1, and now the latest iOS 13 still suffers the same bug using similar technique, which revolves around the activation of FaceTime call and accessing the Siri voiceover feature to enable access to contact list.
The bypass technique also works on iOS 13 GM which runs on iPhone X, albeit access to photos is denied on the device, but ordinarily, the procedure requires physical access to the iPhone, and the enabling of voiceover by initiating a FaceTime call.
And perhaps, this latest bug is inline with a long list of lockscreen bypass bugs on iOS, which started from iOS 6.1 & 7 far back in 2013, that allowed just anyone access to iPhone contact information and even saved photos. Even on the iOS 8.1 and iOS 12.1, the lockscreen can also be bypassed using same procedure.
But the good news is that Apple is already working on the permanent fix, which is expected in the iOS 13.1 beta, which is planned for release on September 30th.
