CVE-2026-19426Network attack vector

Unauthenticated system access and operation via undisclosed endpoint

Published Aug 12, 2026 · Updated Aug 12, 2026

Missing authentication in FitSoft POS System allows remote attackers to access and operate the system without credentials. TWCERT/CC has not disclosed the affected endpoint or the authentication check omitted when requests reach critical functions. Network reachability alone is sufficient; successful requests grant direct system access and operational control, with no reported service interruption.
