CVE-2024-40631— Plate 安全漏洞

Cross-site Scripting (XSS) in media embed element when using custom URL parsers in plate media

Plate media is an open source, rich-text editor for React. Editors that use `MediaEmbedElement` and pass custom `urlParsers` to the `useMediaState` hook may be vulnerable to XSS if a custom parser allows `javascript:`, `data:` or `vbscript:` URLs to be embedded. Editors that do not use `urlParsers` and consume the `url` property directly may also be vulnerable if the URL is not sanitised. The default parsers `parseTwitterUrl` and `parseVideoUrl` are not affected. `@udecode/plate-media` 36.0.10 resolves this issue by only allowing HTTP and HTTPS URLs during parsing. This affects only the `embed` property returned from `useMediaState`. In addition, the `url` property returned from `useMediaState` has been renamed to `unsafeUrl` to indicate that it has not been sanitised. The `url` property on `element` is also unsafe, but has not been renamed. If you're using either of these properties directly, you will still need to validate the URL yourself. Users are advised to upgrade. Users unable to upgrade should ensure that any custom `urlParsers` do not allow `javascript:`, `data:` or `vbscript:` URLs to be returned in the `url` property of their return values. If `url` is consumed directly, validate the URL protocol before passing it to the `iframe` element.

在Web页面生成时对输入的转义处理不恰当(跨站脚本)

Plate 安全漏洞

Plate是Ziad Beyens个人开发者的一个插件系统，可以更容易地构建功能齐全的编辑器。 Plate存在安全漏洞，该漏洞源于当编辑器使用 MediaEmbedElement 组件，并通过 useMediaState 钩子传递自定义的 urlParsers 时，如果自定义解析器允许嵌入 javascript:、data: 或 vbscript: 协议的 URL，就可以受到跨站脚本攻击。
