Description
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.
