Elementor 网站构建器 WordPress 插件在 4.3.5 版本之前未对 SVG 文件的文本内容进行净化处理，仅检查了其元素和属性。这导致拥有“贡献者”（Contributor）角色及以上权限的用户能够存储恶意载荷；当该 SVG 在页面中以内联方式渲染时，载荷会被触发并在任何查看该页面的用户的浏览器中执行。该漏洞仅影响基于 Chromium 的浏览器；Firefox 不受影响。

The Elementor Website Builder WordPress plugin before 4.3.5 does not sanitize the text content of SVG files, checking only their elements and attributes, allowing users with the Contributor role and above to store a payload which breaks out when the SVG is rendered inline in a page and executes in the browser of any user viewing it.
