hackney is vulnerable to Insufficiently Protected Credentials

This Affects:
hackneyTL;DR
Affected versions of this package forward authorization headers and credentials when following redirects to a different host, which could lead to credential leakage if a server redirects requests to an untrusted destination. The patched version stops forwarding sensitive headers on cross-host redirects, preventing unintended exposure of credentials.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
hackney is vulnerable to Insufficiently Protected Credentials in versions 0.0.1 - 2.0.1.
How to fix this
