PHPGurukul Hospital Management System v4.0 contains a Privilege Escalation vulnerability. A low-privileged user (Patient) can directly access the Administrator Dashboard and all sub-modules (e.g., User Logs, Doctor Management) by manually browsing to the /admin/ directory after authentication. This allows any self-registered user to takeover the application, view confidential logs, and modify system data.
