Description
Publii CMS v0.46.5 (build 17089) allows persistent Cross-Site Scripting (XSS) via unsanitized input in configuration fields such as "Site Description" and "Footer Follow Buttons". An attacker can inject arbitrary JavaScript, which is stored in the project and executed in the browsers of remote visitors viewing the generated static site.
