Summary

An issue has been discovered in Novastar-VNNOX-iCare Novaicare 7.16.0 that gives attacker privilege escalation and allows attackers to view corporate information and SMTP server details, delete users, view roles, and other unspecified impacts. NOTE: As of April 2026, the vendor has officially decommissioned the affected legacy endpoints and associated services. The vulnerability is mitigated as the functional logic is no longer operational and the URLs have been removed from production.
