How to Fix CVE-2024-32472
To remediate this vulnerability, upgrade all affected @excalidraw/excalidraw dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install @excalidraw/excalidraw@0.16.4npm install @excalidraw/excalidraw@0.17.6Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @excalidraw/excalidrawHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2024-32472, inspect your project dependencies using npm:
npm ls @excalidraw/excalidrawAnalyze the terminal output to locate any version of @excalidraw/excalidraw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.16.4), your application is affected.
Note: The npm ls @excalidraw/excalidraw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

"details" : "### Summary\n\nA stored XSS vulnerability in Excalidraw's web embeddable component. This allows arbitrary JavaScript to be run in the context of the domain where the editor is hosted. \n\n### Poc\n\nInserting an embed with the below url (can be copy/pasted onto canvas to insert as embed) will log `42` to the console:\n\n```\nhttps://gist.github.com/vv=v<script>console.log(42)</script>\n```\n\n### Details\n\nThere were two vectors. One rendering untrusted string as iframe's `srcdoc` without properly sanitizing against HTML injection. Second by improperly sanitizing against attribute HTML injection. This in conjunction with allowing `allow-same-origin` sandbox flag (necessary for several embeds) resulted in the XSS.\n\nFormer was fixed by no longer rendering unsafe `srcdoc` content verbatim, and instead strictly parsing the supplied content and constructing the `srcdoc` manually. The latter by sanitizing properly.\n\nThe `allow-same-origin` flag is now also set only in cases that require it, following the principle of least privilege.\n\n### Impact\n\nThis is a cross site scripting vulnerability, for more information, please see: https://portswigger.net/web-security/cross-site-scripting\n\nTwo npm `@excalidraw/excalidraw` stable version releases were affected (`0.16.x`, `0.17.x`), and both are now patched.",
