Left a similar comment on another PR, but wondering if/when this will be published to npm? And if we will get an updated version for both v5 and v6, since there seem to have been PRs to address the issue in both versions. Thanks.

I believe this will also require further updates to change the dependency versions for the @AWS-SDK packages to 3.621.0, since the older versions have a forced dependency on the vulnerable fast-xml-parser version.
