CVE-2026-27012: OpenSTAManager affected by unauthenticated privilege escalation via modules/utenti/actions.php

March 3, 2026

A privilege escalation and authentication bypass vulnerability in OpenSTAManager allows any attacker to arbitrarily change a user’s group (idgruppo) by directly calling modules/utenti/actions.php. This can promote an existing account (e.g. agent) into the Amministratori group as well as demote any user including existing administrators.
