What changed and why

Adds the --allow-private-registry CLI option to allow enterprise adopters using internal mirrors (e.g. Nexus, Artifactory) to opt out of the private IP restriction.

Changes

• src/cli/flags.ts: exports FLAG_ALLOW_PRIVATE_REGISTRY = "--allow-private-registry".
• src/cli/help.ts: documents the flag in CLI --help.
• src/cli/args.ts: parses --allow-private-registry into options.allowPrivateRegistry.
• src/utils/effective-options.ts: records allowPrivateRegistry in effective options.
• src/scanner.ts: plumbs options.allowPrivateRegistry to configureNpmRegistry.
• tests/cli/allow-private-registry.test.ts: CLI argument parsing and propagation tests.

Verification

• npm test -- tests/cli/: all 15 test suites / 154 tests passed.
• node scripts/typecheck-changed-tests.mjs upstream/main: clean (0 new errors).

Part of #1571

Summary

Summary by CodeRabbit

• New Features
  • Added the --allow-private-registry option to let configured npm registries resolve to private or reserved IP addresses. The option is off by default.

The CLI now accepts --allow-private-registry and carries its value through effective options to npm registry configuration. The configuration stores the value, which defaults to false. Help text and tests cover the option and its propagation.

Changes: Private Registry Option

Layer / File(s)	Summary
Define and parse the option src/types.ts, src/cli/flags.ts, src/cli/args.ts, src/cli/help.ts, src/utils/effective-options.ts	The CLI defines and parses --allow-private-registry, documents the flag, and records its value in parsed and effective options. The effective value defaults to false.
Pass and store the option src/remediation/npm-registry.ts, src/scanner.ts, tests/cli/allow-private-registry.test.ts	scanPackages passes the option to configureNpmRegistry. That function stores the value and exposes it through isAllowPrivateRegistries. Tests cover parsing, effective-option values, and registry configuration.

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

Merge Risk: Moderate · up to 33437

The new option does not control private-registry access: requests remain permitted when it is omitted. Implement the advertised default restriction before merging, rather than presenting the flag as an effective security control.

Full details: Title check

Explanation

The title uses the required "type: short description" form with the feat type and lowercase text after the colon. It has no trailing period. It names the new --allow-private-registry flag and its purpose, which matches the main change in the changeset. The title uses "feat(cli):" with a scope, which is a small deviation from the "feat:" form in the requirements. The type itself is valid.

Full details: Out of Scope Changes check

Explanation

I found no unrelated change. Each changed file supports the --allow-private-registry option. That option is the second item in #1571. The changes are: the FLAG_ALLOW_PRIVATE_REGISTRY constant in src/cli/flags.ts, the help entry in src/cli/help.ts, parsing in src/cli/args.ts, the optional property in src/types.ts, recording in src/utils/effective-options.ts, plumbing in src/scanner.ts, the stored value and accessor in src/remediation/npm-registry.ts, and the CLI tests. The npm-registry.ts diff adds only the allowPrivate state and accessor. It does not change unrelated registry behavior. The gap is that the flag has no effect yet. That gap belongs to the linked-issue assessment, not to out-of-scope work.

Full details: Description check

Explanation

The description covers what changed and why: it adds the --allow-private-registry opt-out for internal mirror users and lists each touched file with its role. It also reports test and typecheck results. It keeps the template's 'What changed and why' heading and includes the 'Part of #1571' reference. It does not use the template's 'Closes #' line, which is a reasonable choice because the PR does not fully resolve #1571. The PR objectives note that the validateUrlSafe registry-URL validation requested in #1571 is not implemented here, so the description should say this plainly. The verification section is clear and specific.

Full details: Linked Issues check

Explanation

For users, this PR adds the opt-out flag but does not add the protection that #1571 asks for. Repo-configured registries still receive requests with no private-address check. I checked two requirements from #1571.

Requirement 1, not met: validate repo-configured registry URLs with validateUrlSafe before fetch, rejecting private CIDRs by default. At the reviewed head, doFetchPackument in src/remediation/npm-registry.ts builds the URL from registryForPackage(registryConfig, packageName) and calls fetch(url) directly. It makes no validateUrlSafe call. The PR diff for this file adds only allowPrivateRegistries state, an allowPrivate parameter on configureNpmRegistry, and isAllowPrivateRegistries(). The inspected fetch path does not read that value. src/utils/registry-config.ts at head also does no URL validation. resolveRegistryConfig returns the NPM_CONFIG_REGISTRY, .npmrc, or .yarnrc.yml value unchanged. I did not inspect the validateUrlSafe definition. Its existence comes from the issue text.

Requirement 2, met: the --allow-private-registry option. The flag is parsed in src/cli/args.ts, documented in src/cli/help.ts, typed in src/types.ts, recorded in src/utils/effective-options.ts, and passed from src/scanner.ts to configureNpmRegistry. Tests are in tests/cli/allow-private-registry.test.ts.

The PR description uses Closes #1571. That overstates coverage, because the validation requirement is not implemented.

Resolution

1. In doFetchPackument (src/remediation/npm-registry.ts), call validateUrlSafe on the resolved registry URL before fetch(url). Return a non-fetch failure when the check rejects the URL. Apply the check to scoped registry URLs too, since registryForPackage can return a per-scope value.
2. Skip the rejection only when isAllowPrivateRegistries() returns true. This keeps the opt-out working.
3. Add tests that a metadata endpoint such as 169.254.169.254 and a loopback registry are rejected by default. Add tests that the same URLs pass when the flag is set.
4. Change Closes #1571 to a reference such as Refs #1571 until step 1 lands, or keep Closes only after the validation is merged.

Full details: Closes Keyword Matches Scope

Explanation

I found that Closes #1571 would close the issue while registry requests remain unvalidated. The issue asks for validateUrlSafe before registry fetches, rejection of private CIDRs by default, and an opt-out flag for internal mirrors. This PR adds and stores the flag, but doFetchPackument still calls fetch(url) without validation, and the stored flag does not affect requests.

Resolution

I recommend changing Closes #1571 to Refs #1571, or completing the requested validation and making the flag control the private-registry exception.

Test flag forwarding during a scan.

For users, a future change could silently drop the --allow-private-registry value during a scan. I suggest passing parsed options to scanPackages with and without the flag, then checking isAllowPrivateRegistries() after each scan. Reset the registry configuration afterward.

The current test passes true directly to configureNpmRegistry, so it cannot catch a missing scanner argument.

Enforce the private-registry opt-in

Users can reach a private registry without --allow-private-registry. I suggest enforcing the permission for registry requests and adding tests for both flag states. The flag currently changes only stored state, so it does not restrict those requests.

Thanks @Nachiket-Roy, and good catch. This is already being handled through a private security advisory with a fix in progress there, so I'm closing these two to keep the details out of the public tracker until it ships. You found it independently, and I'll note that when the advisory is published. For anything security-related in future, please use the private reporting route in SECURITY.md rather than a public PR.

[Nachiket-Roy]

Hello @sonukapoor, thanks for handling this, and apologies for opening these publicly. I’ll follow SECURITY.md for security issues from now on.
