CVE-2024-12077Network attack vector

Reflected script execution via unescaped calendar_id parameter

Published Jan 7, 2025 · Updated Apr 8, 2026

Reflected XSS in WpDevArt Booking Calendar products allows remote attackers to execute scripts through crafted calendar_id requests. In admin/views/Reservations.php, the reservation view returns the calendar_id request value in generated HTML without sufficient input sanitization or output escaping. Exploitation requires a user to follow an attacker-crafted link, after which the script runs in that user's browser under the affected site's origin.
