## Technical details

CVE-2026-27556 is a PHP local file inclusion (LFI) vulnerability in the /index.php/ajax/save_iodd_parameters endpoint (CWE-98). The vulnerability requires valid operator-level credentials (low privilege) to exploit. An authenticated attacker can manipulate file include parameters to load and execute arbitrary PHP code, achieving remote code execution with root access. The attack is network-reachable and requires no additional user interaction beyond providing valid credentials. Patches are available in firmware version 1.7.4 and later for affected ICE2-* and ICE3-* models.
