Summary
@udecode/plate-link does not sanitize URLs to prevent use of the `javascript:` scheme
Details
Impact
Affected versions of the link plugin and link UI component do not sanitize URLs to prevent use of the javascript: scheme. As a result, links with JavaScript URLs can be inserted into the Plate editor through various means, including opening or pasting malicious content.
Patches
@udecode/plate-link 20.0.0 resolves this issue by introducing an allowedSchemes option to the link plugin, defaulting to ['http', 'https', 'mailto', 'tel']. URLs using a scheme that isn't in this list will not be rendered to the DOM.
Workarounds
If you are unable to update @udecode/plate-link to version 20.0.0, we recommend overriding the LinkElement and PlateFloatingLink components with implementations that explicitly check the URL scheme before rendering any anchor elements.
