A security team for review site vpnMentor, led by Israeli researchers Noam Rotem and Ran Locar, recently found a publicly accessible AWS-hosted database owned by Autoclerk, a reservation system recently acquired by Best Western Hotels and Resorts Group.

The exposed database contained sensitive personal data for thousands of people around the globe, according to vpnMentor, including their hotel and travel reservations. Among those affected were US government and military personnel.
