Vulnerabilities
- Medium 6.4
CVE-2020-36854subscriber+→ 2.20.02.27
Async JavaScript <= 2.19.07.14 - Authenticated (Subscriber+) Stored Cross-Site Scripting
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).
