CVE-2015-9319unauthenticated · needs a click
The gregs-high-performance-seo plugin before 1.6.2 for WordPress has XSS in the context of an old browser.
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).
