Hi,
First of all, thank you for your amazing support, I'm so very happy with your products and accompanying. Thank you!.
I know, this issue could be out of InspireTheme support scope, but your recommendations can help me so much and I appreciate it.
I know the origin of this problem, really is related with Joomla! core and jQuery, because Joomla! 3.9.x still using an old version of jQuery library (jQuery@1.12.4) and this version has vulnerabilities with medium severity. You can check this in you own Joomla! installation using a tool like Chrome audit (Lighthouse) or you can check that on jQuery's website CHANGELOG too.
Please, check this issues from official Joomla!'s GitHub account:
https://github.com/joomla/joomla-cms/issues/19464
https://github.com/joomla/joomla-cms/pull/20660
InspireTheme templates use UIKit framework and the majority of extensions for Joomla! works with Bootstrap 3.X version --not 2.x version, I tested the compatibility with the latest version of jQuery, changing Joomla!'s /media/jui/js/jquery* files by the latest version of these files and it works properly with my third party extensions.
The problem in matter is related to Joomla!'s update system and /media/jui/js/ because after each update the new installed package replaces these files and all updating work of these files are lost.
I know that is possible unsetting these core scripts from template adding some code statements, but I don't want to make this because it requires changes in the core templates and I prefer your support first.
My question is about the best practices for security risk preventions, this version of jQuery is really vulnerable?. Many websites included inspiretheme.com and joomla.org are using jQuery from default Joomla!'s core (old version), but lighthouse audit tool are clasifing this security advisory as medium risk.
What is your profesional recommendation about this issue?, if this is really a seriouslly security problem, InspireTheme are planning take action on this matter?.
Thank you for your great support, you are the best!,
Cheers,
