Suspicious function found

Defender found suspicious code in the Oxygen plugin, that can be a potential security threat. I’ve contacted the plugin’s developers and they said that there is nothing to worry about. Would you please elaborate on the code that was marked as a potential security threat? Please, advise why the following code can be a threat?

eval(‘return (‘.$logic.’:wink: !== false;’:wink:;

eval(‘ ?>’.$code_php.'<?php ‘:wink:;

eval(” ?>”.$GLOBALS->param_array.”<?php “:wink:;

eval(“?> “.$options.”<?php “:wink:;
