CVE-2023-38049Public exploitNetwork attack vector

Appointment disclosure and modification via unchecked object authorization

Published Jul 9, 2024 · Updated Aug 2, 2024

Broken object-level authorization in Easy!Appointments before 1.5.0 allows remote authenticated users to read, modify, or delete any appointment. The GET, PUT, and DELETE /appointments/{appointmentId} handlers accept a caller-controlled appointment ID without verifying authorization for the referenced record. A customer, provider, or secretary account is sufficient, and successful requests expose appointment details or alter or remove the record.
