[release-4.21] OCPBUGS-116250: Validate chart URL in /api/helm/verify

[fsgreco]

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 .tgz or .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/handlers
• Handler coverage verifies invalid, empty, non-archive HTTP(S), ftp://, and file:// chart URLs are rejected with HTTP 400 before downstream verification is invoked.

Additional info

Original fix: #16786

4.22 backport: #17118

Summary by CodeRabbit

• Bug Fixes
  • Chart verification now validates chart URLs before processing requests.
  • Invalid, unsupported, or incomplete URLs receive a clear 400 error response.
  • Valid OCI and HTTP(S) chart archive URLs continue through the existing verification flow.

Walkthrough

The 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.

Changes

Chart URL validation

Layer / File(s)	Summary
Validate chart URLs before verification pkg/helm/handlers/handlerChartVerifier.go	Added regular expressions and isValidChartURL for OCI and HTTP(S) chart archives. Invalid URLs return HTTP 400 before verification.
Cover accepted and rejected URL formats pkg/helm/handlers/handler_chartVerifier_test.go	Updated valid request bodies and response assertions. Added table-driven tests for valid and invalid chart URLs, including verifier invocation checks.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟠 High · up to 286bd

The endpoint still permits authenticated users to make the console backend request private network destinations, so the intended SSRF protection remains incomplete and should be fixed before merge.

Full details: Description check

Explanation

The description explains the solution and lists relevant automated tests. It omits explicit Analysis, Test setup, Browser conformance, Screenshots, and Reviewer sections, but these omissions are non-critical for this backend-only change.

Full details: Stable And Deterministic Test Names

Explanation

PASS: The pull request adds standard Go testing tests, not Ginkgo tests. All added t.Run titles are fixed descriptive strings such as valid HTTPS tgz and rejects internal IP without tgz. The IP addresses and URLs appear only in test data bodies, not in test titles. No timestamps, UUIDs, generated suffixes, node names, or namespaces appear in the added titles.

Full details: Test Structure And Quality

Explanation

PASS. The changed file uses Go's standard testing package and t.Run; it contains no Ginkgo It, BeforeEach, AfterEach, Eventually, or Consistently blocks. The tests use in-memory HTTP requests and fakes only, so they create no cluster resources and require no cleanup or operation timeouts. New assertions have diagnostic messages, and the grouped status and downstream-call assertions are related to the single URL-validation behavior. The surrounding handler tests use the same standard testing and t.Run patterns.

Full details: Microshift Test Compatibility

Explanation

The pull request adds only standard Go handler tests (func Test...) in pkg/helm/handlers/handler_chartVerifier_test.go. It adds no Ginkgo e2e tests (It, Describe, Context, or When), so the MicroShift API and feature compatibility check does not apply.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The pull request changes only the Helm handler and Go unit tests. The added tests use testing.T and table-driven t.Run; they do not add Ginkgo e2e tests or cluster topology assumptions. SNO compatibility checks are therefore not applicable.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only pkg/helm/handlers/handlerChartVerifier.go and its Go test. The diff adds chart URL validation and test cases. It does not add or modify deployment manifests, operator code, controllers, replicas, affinities, topology spread constraints, node selectors, tolerations, or PDBs. The topology-aware scheduling check is therefore not applicable.

Full details: Ote Binary Stdout Contract

Explanation

The pull request changes only chart URL validation and handler tests. The exact diff adds regex initializers, isValidChartURL, and an early HTTP 400 response; it adds ordinary Test... functions with t.Error/t.Errorf. No main, init, TestMain, suite setup, Ginkgo setup, klog, log, fmt stdout writes, os.Stdout, or output redirection changes appear in the changed files. The new top-level initializers only compile regular expressions and define a URL constant. The OTE Binary Stdout Contract is therefore not violated.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

The pull request adds standard Go testing.T unit tests, not Ginkgo e2e tests. The tests use httptest and fake verifier callbacks, so the URL literals do not create external connections. The IPv4 URL appears only as validation-test data. No Ginkgo markers or external network operations were added.

Full details: No-Weak-Crypto

Explanation

PASS: The pull request changes only chart URL validation and related tests in two Helm handler files. The added code imports regexp and uses URL-matching regular expressions; it introduces no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom cryptography, or secret/token comparison logic.

Full details: Container-Privileges

Explanation

The pull request changes only Go handler code and Go tests. The exact HEAD-to-parent diff contains no container or Kubernetes manifest changes and introduces no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, or allowPrivilegeEscalation settings. The internal IP appears only as URL-validation test data.

Full details: No-Sensitive-Data-In-Logs

Explanation

PASS: The pull-request diff adds URL validation and changes handler responses, but it adds no logging calls, logger imports, or log statements. The changed handler contains only JSON decoding, validation, response writing, and existing error formatting. The test changes use t.Errorf, which is test diagnostics rather than application logging. No passwords, tokens, API keys, PII, session IDs, internal hostnames, or customer data are newly written to logs.
