Improper Certificate Validation

aws-crt is a NodeJS/browser bindings to the aws-c-* libraries

Affected versions of this package are vulnerable to Improper Certificate Validation. It appends a user supplied Certificate Authority (CA) to the root CAs instead of overriding it on macOS systems. Additionally, SNI validation is also not enabled when the CA has been “overridden”. TLS handshakes will thus succeed if the peer can be verified either from the user-supplied CA or the system’s default trust-store. Attackers with access to a host’s trust stores or with ability to compromise a CA already in the host's trust store (note: the attacker must also be able to spoof DNS in this case) may be able to use this issue to bypass CA pinning.

How to fix Improper Certificate Validation?

Upgrade aws-crt to version 1.9.0 or higher.
