Instagram Allegedly Downplays Security Vulnerability
Sebastian Guerrero, an independent researcher in Barcelona says he's discovered a way to force friendship with any Instagram user -- private or public -- by exploiting an Instagram server-side vulnerability. In one case, Guerrerro forced Mark Zuckerberg to follow his test account. Then Guerrerro sent him a message through a photo post, which would show up in Zuckerberg's photo feed of people he follows. Guerrero also used a test account to follow a private user without the required approval from the private user.
