Vulnerabilities
- Medium 4.4
CVE-2026-0691admin≤ 1.6.2
CM E-Mail Blacklist <= 1.6.2 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'black_email' Parameter
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).
