\S matches any non-whitespace character, which is very broad. Instead, we are now using \w, which matches [A-Za-z0-9_], and extending it by adding a few special characters to suit our needs.

In my opinion, passwords in URIs can consist of any non-whitespace characters. Using \w limits the match to a specific set of characters, which might exclude valid ones. Are you noticing any detection issues when using \S instead?

e.g. http://username:p%[email protected]" Will not be detected when using \w.

Yes, actually as the scenario mentioned in the linked issue, it matches some special chars like " which it should not I guess. I can add more special characters like %$^... in the set to expand the functionality.
