Hi,
With a little bit of guessing I found an hidden endpoint /api/doctors.php, which is publicly accessible and is leaking some of their private info.

REMEDIATION
Be more careful with managing/removing public endpoints, as they still be fuzzed accessed if no server side prevention is added.
This endpoint should be made just internal only.
