Input validation vulnerability in JS Multi Hotel 2.2.1

The JS Multi Hotel Plugin for WordPress versions up to 2.2.1 is vulnerable to a security flaw called Reflected Cross-Site Scripting. This means that an attacker can use a link to inject malicious code into a website, and if a user clicks on the link, the code will be executed. This is possible because the plugin does not properly sanitize and escape user input. To protect yourself from this vulnerability, make sure you are running the latest version of the JS Multi Hotel Plugin for WordPress.
