invoiceninja is vulnerable to Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

In Invoice Ninja before 4.4.0, there is an unsafe call to unserialize() in app/Ninja/Repositories/AccountRepository.php that may allow an attacker to deserialize arbitrary PHP classes. In certain contexts, this can result in remote code execution. The attacker's input must be hosted at http://www.geoplugin.net (cleartext HTTP), and thus a successful attack requires spoofing that site or obtaining control of it.

Invoice Ninja version 3.8.1 is vulnerable to stored cross-site scripting vulnerability, within the invoice creation page, which can result in disruption of service and execution of javascript code.
