I have find a Reflected XSS vulnerability in this sdk.

The vulnerability exists due to insufficient filtration of user-supplied data in “permToken” HTTP GET parameter that will be passed to “invoice-sdk-php-master/samples/permissions.php”. The infected source code is line 9, there is no protection on $_GET['permToken']; if $_GET['permToken'] contains evil js code, line 9 will trigger untrusted code to be excuted on the browser side.

So if a attacker construct a special url as follow and send it to a victim, when the victim click the url, the code which is contained in the url will be executed on the victim's browser side to do some evil.

The follow scrrenshot is the result to click the upper url ( win7 sp1 x64 + firefox 51.0.1 32bit ):
