What is CVE-2022-4035?

The Appointment Hour Booking plugin for WordPress suffers from an iFrame Injection vulnerability due to inadequate input sanitization and output escaping. This flaw allows unauthenticated attackers to inject malicious iFrame tags through the 'email' or general field parameters. Consequently, whenever a user accesses the booking details page, the injected iFrames will execute, potentially compromising user data and the overall security of the website.
