Easy Appointments contained a very dangerous Broken Access Control vulnerability tracked as CVE-2022-0482 that was exposing PII.

Another day, another threat to your data. The recently discovered CVE-2022-0482 is a Broken Access Control vulnerability affecting Easy Appointments, a popular open-source web app written in PHP, used by thousands of sites to manage their online bookings.

The vulnerability allows unauthenticated actors, to access private users’ data stored in the target system, due to a pitfall in the API permissions check.

The vulnerability was discovered and responsibly reported by Francesco Carlucci on 30th Jan 2022, and fixed by Easy Appointments development team on 8 March 2022.Easy Appointments is now secured, so the best way to be protected is to update the software to the last stable version. Alternatively, a patch file is available for download as well – https://github.com/alextselegidis/easyappointments/blob/master/patch.php – and deploys a fix valid for any previous version.

Yet another time, a new security threat reminds us how important is to keep all the software updated and to monitor the security releases for 3rd party libraries we rely on.
