CVE-2026-66708Network attack vector

Unauthenticated data modification and service interruption

Published Aug 6, 2026 · Updated Aug 6, 2026

Missing authorization in BoldGrid Total Upkeep 1.17.2 and earlier allows remote attackers to modify data and interrupt service. Vendor release notes narrow the affected area to emergency-restore metadata storage and cron restore authentication, but neither the CNA nor vendor discloses the endpoint, action, parameter, or missing check. No authentication or user interaction is required; the published assessment reports no confidentiality impact and does not identify the form of service interruption.
