Jenkins 2.527 and earlier, LTS 2.516.2 and earlier does not perform a permission check for the authenticated user profile dropdown menu, allowing attackers without Overall/Read permission to obtain limited information about the Jenkins configuration by listing available options in this menu (e.g., whether Credentials Plugin is installed).
