By using JCasC I have the plugins versions under my control.

So I don't want to disable the security warnings manually every time I create/configure a new Jenkins instance via JCasC.
It should be possible to configure it via JCasC.

The JCasC configuration could be look like this:

security:
  updateSiteWarningsConfiguration:
    ignoredWarnings:
      - 'SECURITY-248'

• Affected class of Jenkins Core:
  • jenkins.security.UpdateSiteWarningsConfiguration.java
• Affected Jenkins configuration file:
  • jenkins.security.UpdateSiteWarningsConfiguration.xml

First try to patch UpdateSiteWarningsConfiguration (using @DataBoundSetter see [JCasC Requirements - guide for plugin maintainers](https://github.com/jenkinsci/configuration-as-code-plugin/blob/master/docs/REQUIREMENTS.md) ) has failed.
So any hint would be welcome.
