A race condition during Jenkins 2.81 through 2.94 (inclusive); 2.89.1 startup could result in the wrong order of execution of commands during initialization.

Users who cached their CLI authentication before Jenkins was updated to 2.150.2 and newer, or 2.160 and newer, would remain authenticated in Jenkins 2.171 and earlier and Jenkins LTS 2.164.1 and earlier, because the fix for CVE-2019-1003004 in these releases did not reject existing remoting-based CLI authentication caches.

Jenkins Role-based Authorization Strategy Plugin 3.0 and earlier does not properly invalidate a permission cache when the configuration is changed, resulting in permissions being granted based on an outdated configuration.
