Prior to 9.3.5, a business logic flaw (Broken Access Control) in EspoCRM 9.3.3 allows low-privileged users to pin arbitrary notes without having the required edit permissions for the parent object. Due to a \"write first, authorize later\" execution flaw in the backend API, even though the server correctly returns a 403 Forbidden error, the targeted note\u0027s pinned status is already persistently modified in the database. The root cause lies in the server-side processing of the POST /api/v1/Note/{id}/pin endpoint.
