CVE-2026-27563Network attack vector

Root command execution via crafted data storage request

Published Sep 16, 2026 · Updated Sep 16, 2026

OS command injection in affected IO-Link masters before 1.7.4 allows remote authenticated users to execute commands as root. The /api/datastorage/data handler processes attacker-controlled GET-request data without safely neutralizing shell metacharacters before command execution. Administrator credentials and network access to the management API are required; successful exploitation grants root-level control of the device.
