CVE-2026-27556
HighCVSS 8.8Summary
A low-privileged remote attacker can exploit a local file inclusion vulnerability in the /index.php/ajax/save_iodd_parameters endpoint using a valid operator cookie, allowing execution of arbitrary PHP code on the device.
Risk Assessment
Arbitrary PHP code execution can lead to full device compromise, including data theft, system modification, or use of the device for further attacks.
Recommendation
Apply vendor patches as soon as possible and restrict access to the endpoint to trusted operators only.
