- High 8.8
CVE-2017-18510unauthenticated · needs a click
The custom-sidebars plugin before 3.1.0 for WordPress has CSRF related to set location, import actions, and export actions.
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).
