What is CVE-2021-32101?

The Patient Portal of OpenEMR version 5.0.2.1 is vulnerable due to an improper access control mechanism located in portal/patient/_machine_config.php.

Once registered, attackers can access and manipulate sensitive data belonging to all registered patients, posing significant risks to patient privacy and security.
