Description
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 instead consume the url property directly may also be vulnerable if the URL is not sanitised.
