{"id":"CVE-2026-111870","kind":"vulnerability","aliases":["CVE-2026-111870"],"related":[],"title":"Online-Examination-System: missing authentication in admin isAdmin function","description":"A security flaw has been discovered in itsmeravitejak Online-Examination-System up to e6208e630b14657999bbfe4c9912302d2a1e2449. The affected element is the function isAdmin of the file admin/admin.php. Performing a manipulation results in missing authentication. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available. The project was informed of the problem early through an issue report but has not responded yet.","summary":"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.
