Description The plugin does not have CSRF check in some places, and is missing sanitisation as well as escaping, which could allow attackers to make logged in admin add Stored XSS payloads via a CSRF attack

PoC

Make a logged in admin open an HTML file containing: XSS will trigger on the “KKProgressbar2 Free” menu
