Affected versions of npm url-parse are vulnerable to URL Redirection to Untrusted Site.
Impact
Depending on library usage and attacker intent, impacts may include allow/block list bypasses, SSRF attacks, open redirects, or other undesired behavior.
A specially crafted URL with an '@' sign but empty user info and no hostname, when parsed with url-parse, url-parse will return the incorrect href. In particular,
If the 'hostname' or 'origin' attributes of the output from url-parse are used in security decisions and the final 'href' attribute of the output is then used to make a request, the decision may be incorrect.
Leading control characters in a URL are not stripped when passed into url-parse. This can cause input URLs to be mistakenly be interpreted as a relative URL without a hostname and protocol, while the WHATWG URL parser will trim control characters and treat it as an absolute URL.
If url-parse is used in security decisions involving the hostname / protocol, and the input URL is used in a client which uses the WHATWG URL parser, the decision may be incorrect.
This can also lead to a cross-site scripting (XSS) vulnerability if url-parse is used to check for the javascript: protocol in URLs. See following example:
