GHSA-mjv9-vp6w-3rc9: AWS SDK for Rust will log AWS credentials when TRACE-level logging is enabled for request sending

The aws_sigv4::SigningParams struct had a derived Debug implementation. When debug-formatted, it would include a user’s AWS access key, AWS secret key, and security token in plaintext. When TRACE-level logging is enabled for an SDK, SigningParams is printed, thereby revealing those credentials to anyone with access to logs.

Impact

All users of the AWS SDK for Rust who enabled TRACE-level logging, either globally (e.g. RUST_LOG=trace), or for the aws-sigv4 crate specifically.
