fix: suppress option-shaped package names in fix commands - #1493
An npm alias name is read from the lockfile and, since #1450, matched against advisories by its real name while the fix command keeps the alias. A hostile alias such as --registry=http://127.0.0.1:9/ over axios@0.21.1 therefore produces a HIGH finding whose fix command names an option: the plan prints npm install --registry=http://127.0.0.1:9/@npm:axios@0.33.0, and --fix runs it with the package manager treating it as a registry setting (argument injection, CWE-88). Confirmed against npm 10.8.2: --ignore-scripts=false flips a setting a user may have hardened, and --registry=… redirects dependency fetches for that invocation.
This change suppresses such commands rather than quoting them quoting only stops the shell splitting the token, the package manager still receives --registry=… as an option. Since npm never allows a name that starts with a hyphen, nothing valid is lost.
Behaviour:
a target whose package name begins with - produces no command and is reported as not applied. Normal names are unchanged npm install lodash@4.17.21 renders and runs exactly as before.
Tests:
unit coverage for all four package managers and both builders, and an alias case reproducing the live route: a plan is produced, findSuggestedCommandForFinding returns null, --fix spawns nothing, appliedFixCount is 0 and suppressedCount is 1.

Summary
Summary by CodeRabbit
Bug Fixes
Commands are no longer generated or run for package names beginning with -, including child packages in parent updates.
Mixed fix plans continue to generate and run commands for valid packages.
Suppressed packages are omitted from displayed command targets and summaries.
Improvements
Fix summaries distinguish suppressed packages and exclude them from runnable fix counts.
Fix-result JSON includes a suppressed-target count, defaulting to zero when unavailable.
Fix plans remain visible when all command sections are suppressed, with an explanation.
I updated fix planning and execution to suppress package names that begin with a hyphen. The runner skips those targets and reports the suppression count. Scan output includes the same count.
Changes: Option-shaped package handling
Layer / File(s)
Summary
Command planning and filtering src/utils/package-identity.ts, src/remediation/fix-commands.ts, tests/utils/runner-option-injection.test.ts
Shared helpers identify option-shaped command package names. Fix-command generation and target matching exclude those names, including parent-update child package names. Tests cover suppressed and valid package names.
Suppressed targets and execution results src/utils/fix-runner.ts, tests/remediation/npm-alias-fixes.test.ts
Apply-command generation returns no commands for option-shaped package arguments. The runner executes only runnable targets and reports suppressed targets. Tests cover an option-like npm alias.
Plan and result reporting src/output/printers.ts, src/scan/single-scan.ts
Command summaries exclude suppressed targets from ready-package counts and report the suppression count. Scan fix-result JSON includes suppressedCount, defaulting to zero when no fix result is available.

Thanks @S3DFX-CYBER, and welcome. You were right to chase this, and it's more urgent than the description says: since #1450 merged yesterday, a package installed under an npm alias is matched against advisories by its real name while the fix command keeps the alias. An alias named --registry=http://127.0.0.1:9/ over axios@0.21.1 gets a HIGH finding on main, the plan prints npm install --registry=http://127.0.0.1:9/@npm:axios@0.33.0, and --fix runs it with npm treating it as a registry setting. So the runner guard you added is exactly the right idea. A few things before it can go in:
When the guard drops a target, the --fix summary still counts it as applied ("Applied fixes: 1" plus the version line). Could that target be reported as not applied, with a short reason, so the output matches what actually ran?
The title and description could say what it does now, suppressing option-shaped package names, and drop the "latent" framing, since the alias route makes it reachable.

Add a --fix test for suppressed option-shaped targets.
The new tests call only buildApplyCommands and buildTargetCommand. No test sends an option-shaped package through applyFixesIfRequested, and no test checks the suppressed count. A regression that spawns a command for such a target, or that miscounts suppressed targets, would pass the suite.
Add one test to tests/fix-runner-apply.test.ts, using the existing plan, target, recordingRunner, and options helpers. The test should:
Build a plan with one direct target whose package starts with --, such as --ignore-scripts=false.
Run it through applyFixesIfRequested.
Assert that no command runs.
Assert that the applied count is 0.
Assert that the reported suppressed count is 1.
The test depends on the filter call on line 276 being corrected first.

Thanks @S3DFX-CYBER, the main fix works now. On the alias example from last round, --fix runs nothing, package.json is untouched, and the summary says Applied fixes: 0 with Suppressed (package name looks like an option): 1. A few things before it can go in:
CI is red with two failures. The new test calls tBeNull() instead of toBeNull(). And printFixModeSummary prints Not auto-applied: NaN when suppressedCount isn't set, which is what the existing summary test hits. Could the sum treat a missing count as 0, or the test pass one?
The fix plan still says 1 command group ready across 1 package and lists the target under "High severity direct fixes", with no command under it. Could suppressed targets be left out of that count, with a short line saying why there's no command?
The "looks like an option" check is written twice, once in the fix-command builder and once in the runner. Could both use one shared helper?
Small tidy-ups: one if lost its indentation, there's trailing whitespace after a {, and a couple of comment typos ("by the,", "package manager , follows").
The title and description still call this latent and say no finding is produced today. Since #1450 that isn't true. Could they say what it does now, as asked last time?

Thanks @S3DFX-CYBER, the empty check is right now and the rest reads well. One small thing left from my last note, plus a whitespace tidy-up, then this is good to go.

Thanks @S3DFX-CYBER, the guard itself is solid. I ran a lockfile with an alias named --registry=http://127.0.0.1:9/ over axios 0.21.1: on main it prints npm install --registry=...@npm:axios@0.34.0 in the terminal, JSON, SARIF, HTML and the SBOM, and --fix hands it to npm. On your branch that string appears nowhere and --fix never calls npm for it. That's the important part, and it works.
What's left is mostly about how the skip is disclosed, plus one last whitespace bit. Since #1450 shipped in 1.41.0 this will get an advisory pointing at this PR, so I'd like it to be the version we're happy to point at.
The reason will be displayed to describe this comment to others. Learn more.
Thanks @S3DFX-CYBER, moving these into skipped was the right call. The latest push doesn't build, though, which is why CI is red: printers.ts still has a few lines from the old approach that use names it no longer imports, and create-pr.test.ts has a syntax error. Details are inline.
I removed those leftover lines locally to see how the design behaves, and it's what I was after. With the --registry=http://127.0.0.1:9/ alias over axios 0.21.1, no install or update command carrying that string shows up in the terminal, --json, SARIF, the HTML report or either SBOM. --fix never calls npm, where main runs npm install --registry=http://127.0.0.1:9/@npm:axios@0.34.0. --verbose prints "Package name ... looks like a command-line option, so no fix command is offered" under the skipped list, and the JSON and the report carry the same entry. The rename, the required field and the original note wording are all in too, thanks.
What's left: the build fix, a double count in the fix summary, the two whitespace bits from last time, and tests for the new disclosure. tests/fix-runner-summary.test.ts isn't in this PR, but it needs optionShapedNameCount: 0 added to its fixture now that the field is required, otherwise "Not auto-applied" prints NaN and that test fails.
On tests: if I take out the parent-upgrade, transitive-refresh or chain-resolution names from the plan check, or set the count to 0, or remove the summary line, or drop the optionShapedName flag on the skip, everything still passes. One test that asserts the alias lands in plan.skipped with optionShapedName: true and that reason, and that --fix reports optionShapedNameCount: 1, plus a parent-upgrade finding whose recommended parent is option-shaped, would pin all of it.
