Booking denial of service via unchecked end time
Published May 7, 2025 · Updated May 12, 2025
Denial of service in Easy!Appointments 1.5.1 allows remote attackers to block future booking availability with a crafted appointment. Booking::register trusts the submitted appointment end_datetime instead of deriving it from the selected service duration, permitting a far-future value. No authentication is required; one accepted appointment can reserve the provider's remaining calendar and interrupt future bookings.
