Answer in brief
CVE-2026-57223 records a Unknown severity vulnerability in Suricata windows: unquoted LocalSystem service ImagePath can allow local privilege escalation. The current sources do not mark it as known exploited. The current feed maps OISF/suricata (generic). Check affected ranges and fixed versions before updating.

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.17 and 8.0.6, the Windows service installation and parameter-update logic in src/win32-service.c can pass an unquoted service ImagePath to CreateServiceA. When Suricata is installed below a path containing spaces and an earlier path component is writable by a local low-privileged attacker, Windows can execute an attacker-controlled program as LocalSystem, resulting in local privilege escalation. This issue is fixed in versions 8.0.6 and 7.0.17.
