Security researcher Dan Melamed discovered a critical Pinterest vulnerability that “could have spelled disaster in the hands of a black hat” Melamed found a flaw that could be exploited to reveal the email address of any Pinterest user. The security team at Pinterest acted quickly to patch the hole and to protect its users’ privacy. It then added Melamed to the Heroes of Pinterest list and gave him permission to disclose the exploit. The social media site came out of nowhere and “emerged as a power player” for driving website traffic.”]
