Input validation vulnerability in WP Visited Countries Reloaded 3.1.0

The WP Visited Countries Reloaded plugin for WordPress is vulnerable to a security issue called Reflected Cross-Site Scripting. This means that versions up to 3.1.0 of the plugin do not properly protect against malicious code being put into the website. This malicious code could be activated by tricking a user into clicking on a link. As a result, a user’s device could be compromised.
