CVE-2026-1932Network attack vector

Unauthenticated appointment status modification via missing capability check

Published Feb 14, 2026 · Updated Feb 14, 2026

Missing authorization in BS Software Appointment Booking Calendar Plugin – Bookr 1.0.2 and earlier allows remote attackers to alter appointment status. The update-appointment REST API endpoint applies status changes without checking a WordPress capability, leaving appointment authorization unenforced. No authentication is required, so any network client that can reach the endpoint can change the workflow state of any appointment; no confidentiality or availability impact is reported.
