CVE-2024-1634Network attack vector

Unauthenticated service disconnection via missing capability check

Published Jun 18, 2024 · Updated Apr 8, 2026

Missing authorization in Scheduling Plugin – Online Booking for WordPress 3.5.10 and earlier allows remote attackers to delete service connection data. The cbsb_disconnect_settings function performs the disconnect operation without checking a WordPress capability before removing the stored Start Booking connection. Unauthenticated network access is sufficient to sever the site's booking-service link and remove its connection data, interrupting the integration without granting broader site control.
