Summary: Improper permission checks allow canceling queue items and aborting builds in Jenkins

Details: Jenkins 2.299 and earlier, LTS 2.289.1 and earlier allows users to cancel queue items and abort builds of jobs for which they have Item/Cancel permission even when they do not have Item/Read permission. Jenkins 2.300, LTS 2.289.2 requires that users have Item/Read permission for applicable types in addition to Item/Cancel permission. As a workaround on earlier versions of Jenkins, do not grant Item/Cancel permission to users who do not have Item/Read permission.
