NBC NEWS - Mar 28 - Grindr suffers from two security issues, according to Trever Faden, CEO of the property management startup Atlas Lane. He created a website called C*ckblocked that allowed users to see who blocked them on Grindr after they entered their Grindr username and password. Once they did so, Faden was able to gain access to a trove of user data that is not publicly available on user profiles, including unread messages, email addresses, deleted photos, and the location data of users, some of whom have opted to not share their locations publicly. Faden also discovered a separate security flaw related to location data that did not require users to log in to any third-party apps or websites with their Grindr credentials. Grindr said it was aware of the vulnerabilities and had changed its system. This is not the first time that issues with Grindr's security around location data has been reported.
