# Online-Examination-System: missing authentication in admin isAdmin function

The itsmeravitejak Online-Examination-System has a flaw in the isAdmin function of admin/admin.php where authentication is missing, so remote requests can reach admin functionality. A public exploit exists, and the sources say the vendor has not responded.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Look at `admin/admin.php` in the deployed copy and check whether the `isAdmin` function verifies a session or role before running.
- Compare the repository commit against `e6208e630b14657999bbfe4c9912302d2a1e2449`; the sources say the project uses rolling releases with no version numbers.
