The Chrome browser has an XSS security audit function that analyzes the HTML submitted via the form values and blocks these requests from XSS so that forms are never submitted and any XSS exploit is avoided. The problem is that since version 57 of Chrome, it has started blocking POST submissions with some HTML structures. A Chrome error message with the name ERR_BLOCKED_BY_XSS_AUDITOR is displayed and the form is not sent at all.

How to Fix Error Message ERR_BLOCKED_BY_XSS_AUDITOR

Add Some Page Headers

If you are a website administrator and this error message occurs during normal use, you can try to delete it by adding some page headers to the POST headers. This is a temporary solution until you can find an appropriate alternative that correctly handles the XSS auditor’s request.

  • Add the following header to your PHP file: header(‘X-XSS-Protection:0’) ;
  • To temporarily disable XSS protection, use HttpContext.Response.AddHeader(“X-XSS-Protection”,”0″);
  • Configure the Web file Config,
    <system.webServer>
    <httpProtocol>
    <customHeaders>
    <add name=”X-XSS-Protection” value=”0″ />
    </customHeaders>
  • Add request validation, var code = Request.Unvalidated.Form[“code”];
  • To turn-off web.config, <httpRuntime requestValidationMode=”2.0″/>
