ITPRO.CO.UK - Dec 4 - Security researchers have found major Android apps used by hundreds of millions of people, such as Grindr, Bumble, OKCupid are vulnerable to a known flaw that could give attackers access to the app users' phones and data. The security flaw is in Google's widely used Play core library, which lets developers push in-app updates and new feature modules to their Android apps. Google fixed the flaw in April 2020, but the app developers must also install the updated Play core library in their apps to eliminate the threat. Many developers have not yet done this.
