Overview

@actions/http-client is an actions-http-client.

Affected versions of this package are vulnerable to Information Disclosure. Actions Http-Client can disclose Authorization headers to incorrect domain in certain redirect scenarios. The conditions in which this happens are if consumers of the http-client:

  1. make an http request with an authorization header
  2. that request leads to a redirect (302) and
  3. the redirect url redirects to another domain or hostname

Then the authorization header will get passed to the other domain.
