The access label is read from the record's own text (e.g. “subscriber+”: subscriber and above). When the text names no role, CVSS decides between “login required” and “high privilege”; no role name is invented. “Needs a click”: the attack depends on a logged-in user following a link (CSRF, reflected XSS).
