Google revealed Monday that its soon-to-be shuttered social network suffered from another security lapse, a software bug that could have allowed third-party apps and developers to gain access to 52 million users’ personal information without their permission. For six days in November, an update to the underlying code of Google+ meant that apps seeking to access users’ profile information-including their names, email addresses, occupations and ages — could view that data even if it was “set to not-public,” Google said in a blog post.
