Detailsinfo

A vulnerability classified as problematic was found in udecode plate up to 36.0.9. This vulnerability affects the function MediaEmbedElement. The manipulation of the argument urlParsers with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2024-40631 since 07/08/2024. The exploitation appears to be easy. The attack can be initiated remotely.
