Vulnerability from github

Severity
Summary
Leading white space bypasses protocol validation
Details
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
}
