  - follow-redirects is an open source, drop-in replacement for Node's `http` and `https` modules that
    automatically follows redirects. Prior to 1.16.0, when an HTTP request follows a cross-domain redirect
    (301/302/307/308), follow-redirects only strips authorization, proxy-authorization, and cookie headers
    (matched by regex at index.js). Any custom authentication header (e.g., X-API-Key, X-Auth-Token, Api-Key,
    Token) is forwarded verbatim to the redirect target. This vulnerability is fixed in 1.16.0.
