This flaw allows a user holding the Overall/Manage permission, rather than full Overall/Administer privileges, to submit a crafted project naming strategy configuration that causes Jenkins to instantiate arbitrary configuration-related object types, including types intended for administrator-only configuration. This weakens the separation between the Overall/Manage and Overall/Administer permissions. Exploitation requires an authenticated user who already holds the Overall/Manage permission, which is not granted by default and is typically reserved for trusted operators, limiting the practical impact.
