Is possible to bypass my regex and execute any javascript?
function json(a){
if (/^\s*$/.test(a) ? 0 : /^[\],:{}\s\u2028\u2029]*$/.test(a.replace(/\\["\\\/bfnrtu]/g, "@").replace(/"[^"\\\n\r\u2028\u2029\x00-\x08\x0a-\x1f]*"|true|false|null|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?/g, "]").replace(/(?:^|:|,)(?:[\s\u2028\u2029]*\[)+/g, "")))
try{
return eval("(" + a + ")")
} catch (b) {}
g(Error("Invalid JSON string: " + a))
}
json(window.name);
