There has been a security bug in nginx which affected some of the old version. We have given a proper time to update the nginx version of all our nginx plugins to our clients. We also updated the default nginx installation of our cpnginx plugin to version 1.22.1 .
We always recommend to chose the stable version of nginx on your production servers. So if you are using any version below stable 1.22.0 or current 1.23.1 , it is recommend to upgrade to version 1.22.1 stable or 1.23.2 release version.
To know more about this bug please read Nginx security advisory from https://nginx.org/en/security_advisories.html
