CyberRota Analysis

AI-Generated

Easy!Appointments versions prior to 1.6.0 are vulnerable due to insufficient verification of user privileges in the appointment management endpoints, allowing authenticated providers to manipulate appointments in other providers' schedules. This could lead to unauthorized access and modification of sensitive scheduling data, posing a risk to user privacy and operational integrity. Organizations using affected versions should prioritize upgrading to 1.6.0 to mitigate this vulnerability.

Original NVD Description

Easy!Appointments is a self hosted appointment scheduler. Versions prior to 1.6.0 correctly filter provider-scoped appointments in the `appointments/search` response, proving that provider isolation is an intended security boundary. However, the direct mutation endpoints `appointments/store` and `appointments/update` only check generic appointment privileges and never verify that the submitted `id_users_provider` belongs to the current session. A normal authenticated provider can inject new appointments into another provider's schedule via `store`, or reassign existing appointments into a foreign provider's calendar via `update`. The `store` path contains an additional write-before-crash bug: the unauthorized row is committed to the database before the controller crashes on a type error, so the attacker receives an error response while the foreign appointment is already persisted. Version 1.6.0 patches the issue.
