CVE-2026-27555Network attack vector

Authenticated PHP execution via local file inclusion

Published Sep 16, 2026 · Updated Sep 16, 2026

Local file inclusion in affected IO-Link masters before 1.7.4 allows remote authenticated users to execute arbitrary PHP code. The /index.php/ajax/get_iodd_port_info endpoint includes an attacker-selected local file in PHP processing without adequately constraining the file reference. Exploitation requires a valid low-privileged user cookie and grants code execution in the device context.
