@udecode/plate-link is the link handler for the udecode/plate rich-text editor plugin system for Slate & React. 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. `@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. Users are advised to upgrade. Users unable to upgrade are advised to override the `LinkElement` and `PlateFloatingLink` components with implementations that explicitly check the URL scheme before rendering any anchor elements.
