Vulnerability nof fixed on Premium version

I’ve sent multiple emails to @never5 and @barrykooij & to their contact form and had to take the updated code from this free version of the plugin, that resolves the vulnerability in the Version 1.9.0 as per https://wpscan.com/vulnerability/7593d5c8-cbc2-4469-b36b-5d4fb6d49718 and update it manually in the premium version 1.9.0

No problem about blocking the plugin from working if the annual fee isn’t paid but nobody is there to fix a known vulnerability, very professional. Since Apr 3rd when I sent you emails and again on Apr 14th not a word back and still no official update of the premium version.
