PlaciPy is a placement management system designed for educational institutions. In version 1.0.0, the GET /api/students/:email PUT /api/students/:email/status, and DELETE /api/students/:email routes in backend/src/routes/student.routes.ts only enforce authentication using authenticateToken but do not enforce authorization. The application does not verify whether the authenticated user owns the student record being accessed, has an administrative / staff role, or is permitted to modify or delete the target student.
