Input validation vulnerability in Medicare 2.1.0

The Medicare theme for WordPress, up to version 2.1.0, is at risk of a security issue called PHP Object Injection. This happens when untrusted information is processed and can allow hackers to insert malicious code into the system. There is no known way for attackers to exploit this on their own, but if there are additional plugins or themes installed, it could lead to more serious consequences such as deleting files, accessing sensitive information, or running code.
