Comments
I am part of the team that submitted the CVE Request. Due to confusion in communicating versioning, this advisory appears to be incorrect. We marked the CVE as impacting Zowe versions < 1.28.2 or < 2.5.0 which is understood by many of our consumers, but not by automation. We'll fix this going forward. The actual Imperative versions affected are < 4.18.10 or >= 5.0.0, < 5.7.1, and the PRs which fixed the issue were added to the references section. As for verifying my authenticity, I am a Zowe Organization Owner/Administrator and Zowe CLI Squad Member (which owns the Imperative framework). I can provide additional information if required, please let me know if that's the case.

@MarkAckert Before I merge the changes, I have a question about versions 4.18.10 and 4.18.11.
https://github.com/zowe/imperative/commits/v4.18.10 merged changes from PR 900, but changes from PR 901 weren't merged until https://github.com/zowe/imperative/commits/v4.18.11. Is version 4.18.10 considered fixed with just the commits from PR 900?

https://github.com/zowe/imperative/commits/v5.7.1 merged changes from PR 902, which looks like it covers changes from 900 and 901.

Is version 4.18.10 considered fixed with just the commits from PR 900?

That's right 👍 The relevant commit is the one named "Replace execSync with spawnSync" which was present in PR 900. PR 901 is separate and unrelated - it was for npm@9 compatibility.

As for verifying my authenticity, I am also a Zowe CLI Squad Member and admin of the Imperative repository.
