fast-uri vulnerable to host confusion via percent-encoded scheme normalization

Impact fast-uri decodes percent-encoded characters in the scheme component with the legacy global unescape and serializes the result back as raw characters, without re-escaping it or validating it as a scheme. A scheme that decodes to characters outside the RFC 3986 scheme grammar can therefore...

GHSA-J839-GQQ4-GF9J Jodit has incomplete javascript: scheme normalization in sanitizeHTMLElement href check that allows link XSS

Summary jodit's sanitizeHTMLElement neutralizes a javascript: href using a bare href.trim.indexOf'javascript' === 0 check.
