CVE-2026-6888Network attack vector

Authenticated database command execution via SQL injection

Published May 13, 2026 · Updated May 13, 2026

SQL injection in affected Advantech IoTSuite, IoT Edge, SaaS Composer, and WebAccess releases allows remote authenticated users to run database commands. The CNA record refers only to an unspecified interface and does not disclose the parameter or code path that fails to neutralize attacker-controlled SQL input. High-privilege authentication is required, and successful exploitation permits sensitive database data to be read, modified, or deleted.
