### Impact Whitespace characters are not removed from the beginning of the protocol, so URLs are not parsed properly and protocol validation mechanisms may fail.

### Patches Patched in 1.19.9

### Workarounds Remove leading whitespace from values before passing them to URI.parse (e.g. via `.href(value)` or `new URI(value)`), e.g. by using

```js function remove_whitespace(url){ const whitespace = /^[\x00-\x20\u00a0\u1680\u2000-\u200a\u2028\u2029\u202f\u205f\u3000\ufeff]+/; url = url.replace(whitespace, '') return url } ```
