Flaws in Tinder App Put Users’ Privacy at Risk, Researchers Say

Be careful as you swipe left and right—someone could be watching. Security researchers say Tinder isn’t doing enough to secure its popular dating app, putting the privacy of users at risk. A report released Tuesday by researchers from the cybersecurity firm Checkmarx identifies two security flaws in Tinder’s iOS and Android apps. When combined, the researchers say, the vulnerabilities give hackers a way to see which profile photos a user is looking at and how he or she reacts to those images—swiping right to show interest or left to reject a chance to connect.
