Input validation vulnerability in Floating button 5.3.0

The Floating Button plugin for WordPress, used in versions up to 5.3.0, is vulnerable to a type of cyber attack known as Reflected Cross-Site Scripting. This attack makes it possible for unauthorised users to inject malicious code into pages, which can then be executed if users are tricked into clicking a link. To protect against this vulnerability, the Floating Button plugin must be updated to ensure that all inputs and outputs are properly checked and secured.
