Redfin Exposes Users' Personal Info on Listing Contact Forms, Leaving Millions Vulnerable.
A recent security flaw on the online real estate platform Redfin exposed millions of users' personal information on listing contact forms, leaving many vulnerable to potential exploitation. According to a spokesperson for the company, the error was active for less than a week and was remediated as soon as they became aware of it.
The vulnerability allowed other users who logged onto listings to view random users' names, email addresses, and phone numbers momentarily when a contact information form popped up on a listing. However, if JavaScript was disabled in browsers, the personal identification information remained visible even after the initial exposure.
Redfin, with 50 million monthly users according to its parent company Rocket, has faced criticism for not providing adequate security measures to protect user data. The company's privacy policy states that private information may be shared when prompted by a disclaimer, but this was not present on the contact form used in listings.
Experts warn that inadvertently revealing user information is an ongoing problem affecting many web services. In this case, using reverse phone number and email search databases confirmed that the exposed information belonged to real people, not just dummy data.
