The plugin list indicates that you need to perform several plugin maintenance steps. The plugin maintenance steps are displayed in the plugin manager of your Jenkins installation. The maintenance steps include (1) resolve security vulnerabilities by updating plugins and (2) remove deprecated plugins. I think that you should also remove unused plugins like the Ivy plugin and the GitHub pull request builder and the WMI Windows Agents plugin. Once you perform those plugin maintenance steps, the message will no longer appear.

Your current configuration

When I configure a system with Jenkins 2.426.2 and your plugin list, the following message is reported during Jenkins startup:

Plugin maintenance - security warnings

There are security warnings for several of the installed plugins. You should resolve the security warnings by updating the affected plugins to their latest versions or by removing the plugins. The security warnings say:

Plugin maintenance - deprecated plugins

The “Manage Jenkins” page for that configuration shows a warning that you have deprecated plugins installed. The deprecated plugins should be removed. The message is:

The following installed plugins are deprecated
Green Balls
Icon Shim
JavaScript GUI Lib: jQuery bundles (jQuery and jQuery UI) plugin
JavaScript GUI Lib: ACE Editor bundle plugin
Bootstrap 4 API Plugin
JavaScript GUI Lib: Moment.js bundle plugin
Pipeline: Declarative Agent API
JavaScript GUI Lib: Handlebars bundle plugin
DEPRECATED Blue Ocean Executor Info
Visual Studio Code Metrics Plugin

In general, this means that these plugins are either obsolete, no longer being developed, or may no longer work. See the linked web pages for further information about the cause for the deprecation, and suggestions on how to proceed.

Plugin updates to install

In that configuration, there are 27 plugins that need to be updated. Update them. Jenkins maintainers are much more likely to test with the most recent plugin releases. When you choose to upgrade Jenkins without upgrading plugins, you are creating a configuration that is not as well tested as the configuration would be if you updated the plugins.
