scram-client 3.3 fixes a flaw that allows an attacker capable of performing a TLS machine-in-the-middle (MITM) attack to silently downgrade a connection from SCRAM-SHA-256-PLUS (with channel binding)
to standard SCRAM-SHA-256 (without channel binding), bypassing strict client-side enforcement policies.

See GHSA-p9jg-fcr6-3mhf and https://github.com/ongres/scram/releases/tag/3.3

5.1 is not affected because is uses the default "prefer"/"allow" channel binding policy and not the affected "strict" channel binding policy:
