OCPBUGS-59070: CVE-2025-53547 openshift4/ose-operator-sdk-rhel8: Helm Chart Code Execution [openshift-4.15.z]

[PillaiManish]

Description of the change:

Based on the analysis from GHSA-557j-xg8c-q2mm, the vulnerability in operator-sdk is found in the code path leveraging the downloader.Manager.Build() method from Helm SDK. The fix for the CVE is adopted in the recent Helm SDK version 3.18.4. The same helm version is not adopted in the present release-4.15, hence, the PR adds update in the operator-sdk layer to mitigate the vulnerability.

Manual backport of PR: #434 for openshift-4.15.

@PillaiManish, I think there was some issue with the UTs. Did we modify the UTs to make the CI pass? If yes, what were the changes?

Yes, there was some nil pointer for the dependencies --> while i try to download the dependencies, so I just removed one of the test case, testing with normal chart.lock one.

Why it's so for 4.15.z and we don't see this happening for later versions?

[PillaiManish]

Why it's so for 4.15.z and we don't see this happening for later versions?

In the newer code: https://github.com/openshift/ocp-release-operator-sdk/blob/main/vendor/helm.sh/helm/v3/pkg/getter/ocigetter.go#L52-L57
there is handling for registryClient

But in the older version: https://github.com/openshift/ocp-release-operator-sdk/blob/release-4.15/vendor/helm.sh/helm/v3/pkg/getter/ocigetter.go#L40-L43
there is no such handling. So, it throws a nil pointer error.
