Google recently updated Chrome for iOS to support iOS 7 but unfortunately, the new version has a big security flaw that shows private browsing search history in Google mobile search bar. According to TechCrunch, Google has already acknowledged the bug and has said that it’s an “unavoidable loophole that comes with building a browser on iOS”.
It seems that when you use the search/address bar in Incognito mode in Chrome, that history will show up when you return to standard browsing in Google’s mobile website search bar. Google says it has already noted this issue in the support docs around Incognito mode. The security flaw, that was first discovered by UK’s development and design firm Parallax, has also been demonstrated via a simple video walkthrough of the behaviour (embedded below).
“TechCrunch was able to replicate this with our own devices. Note that if you try to search from the combined address/URL bar in non-Incognito mode, you won’t see your search history from when you were browsing in private – you need to navigate to Google.com (or Google.co.uk, etc.) in order to see the history of terms you looked up while supposedly keeping your data and history off the books.”
Here’s a demo of the Incognito bug in Chrome for iOS 7:
