A flaw in popular dating app Tinder that allowed users to find Facebook IDs has been clsoed.

Web developer Shaked Klein Orbach reported that users could discover Facebook IDs depending on the target's Facebook privacy settings and leverage that credential into connecting with and identifying the person.
“We want to thank Mr. Orbach for pointing out a way to create a match with another user through manipulating certain API calls,” Sean Rad, Tinder CEO, told qz.com.
“This issue is now resolved and to our knowledge no one was affected outside of Mr. Orbach's test.”
