Cross-site scripting (XSS) from field and configuration text displayed in the Panel

Kirby is a content management system. In Kirby CMS versions 3.5.5 and 3.5.6, the Panel's `ListItem` component (used in the pages and files section for example) displayed HTML in page titles as it is. This could be used for cross-site scripting (XSS) attacks. Malicious authenticated Panel users can escalate their privileges if they get access to the Panel session of an admin user. Visitors without Panel access can use the attack vector if the site allows changing site data from a frontend form. Kirby 3.5.7 patches the vulnerability. As a partial workaround, site administrators can protect against attacks from visitors without Panel access by validating or sanitizing provided data from the frontend form.

Kirby 跨站脚本漏洞

Kirby是一套基于文件的内容管理系统（CMS）。 Kirby CMS 3.5.5 和 3.5.6存在跨站脚本漏洞，该漏洞源于面板的“ListItem”组件（例如用于页面和文件部分）在页面标题中按原样显示 HTML。
