WalkthroughThe Helm chart verifier now validates OCI and HTTP(S) chart archive URLs before configuration and verification. Invalid URLs return HTTP 400. Tests cover valid URL formats, invalid schemes and hosts, verification invocation, and response bodies. ChangesChart URL validation

github redhat-certification chart-verifier v0.0.0-20250415162918-111669f9d053 verifier Run chart URL
💡 Result:
The version string v0.0.0-20250415162918-111669f9d053 refers to a specific development snapshot (pseudo-version) of the Red Hat chart-verifier tool, which is used to validate Helm charts for Red Hat OpenShift certification [1][2]. To run the chart-verifier against a chart URL, you can use the official container image provided by Red Hat. The standard command structure to verify a remote Helm chart is as follows [3][4]: podman run --rm -i \ -e KUBECONFIG=/.kube/config \ -v "${HOME}/.kube":/.kube:z \ "quay.io/redhat-certification/chart-verifier" \ verify \ In this command: - should be replaced with the actual URL of the Helm chart you wish to verify [3][5]. - The -v flag mounts your local Kubernetes configuration directory so that the verifier can interact with a cluster if required for certain checks (such as those requiring Helm install/test) [3][6]. - You can also run a subset of checks using the -e (or --enable) flag, for example: verify -e images-are-certified,helm-lint [3][4]. If you are running the tool on Linux and have downloaded the binary directly from the official GitHub releases page, you can execute it locally using [3][7]:./chart-verifier verify For further troubleshooting, such as issues with the chart URL or connectivity, you can add the -l flag to enable verbose logging [6]. Detailed documentation on available commands and check types is maintained in the official repository [3][5].

Block private HTTP(S) chart destinations.
httpURLRe accepts http://172.28.1.76:8849/chart.tgz and localhost URLs. HandleChartVerifier passes these URLs to chartverifier.ChartVerifier, whose pinned dependency calls http.Get through loadChartFromRemote without a destination policy. Reject these destinations before verification and enforce the policy on resolved addresses and redirects. Move the private-IP case to the rejected tests and assert that neither action configuration nor verification runs.

@sowmya-sl, I feel like we've seen this "suggestion" before, and it was wrong -- as I recall, we need localhost and certain other URLs local to the cluster to work...is that right?

Seems like the humans are having a chat. I'll hop back into my burrow for now. If you need me again, just tag @coderabbitai in a new comment, and I'll come hopping out!

Thanks for the feedback! I confirm the current implementation already preserves support for localhost, private-IP and cluster-local chart URLs. I’ve added explicit localhost and loopback test cases to document that behavior
Both new cases explicitly ran and passed:
PASS: valid_HTTP_localhost_tgz
PASS: valid_HTTP_loopback_tgz
Reject invalid chart URLs before chart verification to prevent authenticated SSRF. Jira: https://redhat.atlassian.net/browse/OCPBUGS-116250 Assisted-by Chai Bot <chai-bot@redhat.com>

CONSOLE Features and Fixes
Manual backport / adaptation of #17118 for OCPBUGS-116250 to
release-4.21.Solution description
Invalid chart URLs now return HTTP 400 before chart verification begins, preventing the verifier from making an outbound request for invalid input. The validation accepts OCI registry references and HTTP(S) Helm chart archives ending in
.tgzor.tar.gz.The 4.21 Helm code layout lacks the reusable validator used by the 4.22 backport, so this applies the equivalent validation in the verifier handler.
Test cases
go test ./pkg/helm/handlersftp://, andfile://chart URLs are rejected with HTTP 400 before downstream verification is invoked.Additional info
Original fix: #16786
4.22 backport: #17118
