[axios proxy bypass] #ssrf

Axios proxy bypass

  1. The proxy settings are defined in the top level config.
  2. Upon the initial reqest, an httpAdapter is resolved, and within it, the transport type which can be [http(s) (native), follow-redirect.http, follow-redirect.http].
  • When redirects are disabled, the native http transport is chosen
  • When redirects are enabled, then:
    • No proxy is set: follow-redirect.http
    • An http proxy is set: follow-redirect.http
    • An https proxy is set: follow-redirect.https
  1. follow-redirect has 613 npm packages depending on it. Some popular are axios, tinyreq and node-rest-client.
