Concrete CMS version 8 uses jQuery 1.22.2, but this version has officially been marked as the end of life. It has some vulnerabilities, but the jQuery team won't fix them. They announced you should upgrade jQuery 3.5.0 or later.
The core team of Concrete CMS does not plan to update jQuery on version 8.x for backward compatibility. If you can update to Concrete CMS version 9, it'd be best to fix those vulnerabilities. However, if you have to take some time to fix your site to work with version 9 and want to update jQuery immediately, you can override it.
