CVE-2026-71451

OS command execution via undisclosed injection point

Published Oct 1, 2026 · Updated Oct 1, 2026

OS command injection in Johnson Controls EasyIO FS-32 Controller before 3.0b63 allows attackers to execute OS commands via unspecified vectors. The public vendor material does not identify the input, handler, or command construction responsible for the injection. The entry point and required privileges remain undisclosed, so exposure cannot be narrowed beyond controllers running the affected firmware.
