DescriptionCVE.org
WordPress Booking Calendar Contact Form 1.0.23 contains privilege escalation and stored cross-site scripting vulnerabilities that allow authenticated users to modify plugin options and inject malicious scripts by failing to verify user privileges and sanitize input parameters. Attackers with subscriber-level accounts can inject XSS payloads through parameters like price, name, calendar_language, and email_confirmation_to_user via admin-ajax.php and admin.php endpoints to execute arbitrary JavaScript in administrator browsers.
