Mailman 'list templates' and 'list info' Multiple HTML Injection Vulnerabilities

Mailmanのlist templateとlist infoに任意のHTMLを挿入できる脆弱性が存在するそうです。

クッキーベースの認証なので、盗めばいけるみたいです。

Mailman is prone to multiple HTML-injection vulnerabilities because it fails to properly sanitize user-supplied input.
Attacker-supplied HTML and script code could execute in the context of the affected website, potentially allowing an attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user; other attacks are also possible.
