CVE-2024-12737Public exploitNetwork attack vector

Administrator-context script execution via reflected location parameter

Published Feb 26, 2025 · Updated Feb 26, 2025

Reflected XSS in WP BASE Booking before 5.0.0 allows remote attackers to run script in an administrator's browser via a crafted URL. The appointments admin page reflects the app_location_id query parameter into HTML without sanitization or output escaping. Exploitation requires a high-privilege user such as an administrator to open the crafted URL, exposing that user's browser session to script execution.
