Frontier Airlines site leaks all personal info with just a glance at a boarding pass, researcher claims — booking number and last name nets you every passenger's personal info, including address, passport, TSA PreCheck, and most credit card info

A security researcher claims that Frontier Airlines' website is vulnerable to a significant data leak, allowing access to all personal passenger information with just a boarding pass. By obtaining a booking number and last name, unauthorized individuals could allegedly access sensitive data, including addresses, passport details, TSA PreCheck status, and partial credit card information. This alleged vulnerability raises serious concerns about passenger privacy and data security within the airline industry. If confirmed, such a breach could have severe implications for both Frontier Airlines and its customers. The findings highlight the critical need for robust cybersecurity measures in travel systems. Passengers are advised to be cautious about sharing their travel details.
