What changed and why

On a pnpm workspace, fix commands for dependencies declared by the workspace root's own package.json were printed as a bare pnpm add, which pnpm refuses at a workspace root (ERR_PNPM_ADDING_TO_ROOT), so the command failed and the finding stayed.

  • When a pnpm-workspace.yaml sits next to the scanned pnpm-lock.yaml, install targets that land in the root (no non-root workspace member) are marked workspaceRoot.
  • Those targets get pnpm add -w (e.g. pnpm add -w -D vitest@4.1.12) in the plan command, the per-finding command (findSuggestedCommandForFinding, used by JSON/HTML/SARIF), and the --fix argv, so the printed plan and --fix agree. A chain-resolution command for a root target is rebuilt the same way.
  • Member commands (pnpm --filter ./<member> add), within-range pnpm update refreshes, single-project pnpm repos and npm/Yarn/Bun are unchanged.

Tests:

  • tests/remediation/fix-commands-workspace-scoping.test.ts: pnpm workspace fixture with a vulnerable root dev dependency prints pnpm add -w -D vitest@4.1.12; the same lockfile without pnpm-workspace.yaml still prints pnpm add -D vitest@4.1.12; mixed root + member targets add -w only to the root command.
  • tests/fix-runner-apply.test.ts: --fix spawns pnpm add -w -D vitest@4.1.12 for the root target and leaves the --filter ./client one as is.

The root-dev, mixed and --fix tests fail on main. npm run lint:tests, npm run build, node scripts/typecheck-changed-tests.mjs and the full npm test (226 suites) pass.

This change was written with AI assistance and reviewed and tested by me.

Closes #1582

On a pnpm workspace (pnpm-workspace.yaml next to pnpm-lock.yaml), a fix
for a dependency declared by the root's own package.json printed a bare
`pnpm add`, which pnpm refuses with ERR_PNPM_ADDING_TO_ROOT. Install
targets that land in the workspace root are now marked workspaceRoot and
get `pnpm add -w` in the plan command, the per-finding command and the
--fix argv. Member (--filter) commands, single-project pnpm repos and the
other package managers are unchanged.

Closes OWASP#1582

Summary

Summary by CodeRabbit

  • Bug Fixes
    • Fixed dependency installation in pnpm workspaces so root-level dependencies, including development dependencies, are added to the workspace root, while dependencies for individual workspaces remain scoped to the correct workspace.
    • Ensured root-level dependencies are handled consistently in suggested fixes and combined remediation plans, including when multiple workspace targets are involved.
    • Single-project repositories continue to use the standard root install command.

pnpm remediation commands now include -w for dependencies declared at a workspace root. Commands for workspace members remain filtered, and single-project pnpm repositories remain unchanged.

Changes: pnpm workspace-root remediation

Layer / File(s) Summary
Root-target detection and command generation
src/remediation/fix-commands.ts, tests/remediation/fix-commands-workspace-scoping.test.ts
The remediation code detects a sibling pnpm-workspace.yaml and marks eligible targets without a non-root workspace as workspace-root targets. Generated root commands include -w; member commands retain their filters. Tests cover workspace and single-project repositories, mixed root and member targets, and chain-resolution commands.
Applying root-target commands
src/utils/fix-runner.ts, tests/fix-runner-apply.test.ts
The pnpm argument builder adds -w for workspace-root targets with no non-root workspace. A test covers a root dev dependency and a dependency in the client workspace.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Commands now add -w for pnpm workspace-root dependencies, as requested. A package declared by both the workspace root and a member may still be upgraded only in the member while the plan reports it as covered. That gap predates this PR but is worth resolving or accepting before merge.

Explanation

Users can run fixes for root dependencies in a pnpm workspace. The implementation detects pnpm-workspace.yaml beside the lockfile, marks root targets, and adds -w to plan commands, per-finding commands, chain-resolution commands, and --fix argv. Tests cover the root command, unchanged single-project behavior, mixed root and member targets, and --fix behavior. These changes meet #1582.

Full details: Out of Scope Changes check

Explanation

The changes stay within #1582. Source changes only add workspace-root targeting and pnpm command handling. Tests cover the requested root, member, single-project, chain-resolution, and --fix cases. No unrelated package-manager or feature changes are present in the reviewed diff.

Full details: Title check

Explanation

The title accurately describes the change and uses lowercase text without a trailing period, but it does not match the required type format because it uses "fix(remediation):" instead of an allowed type followed directly by a colon.

Resolution

Rename the title to use the required form, such as "fix: add -w to pnpm add for workspace-root dependencies".

Full details: Closes Keyword Matches Scope

Explanation

Users get the root command, but I still cannot confirm the requested root dev-dependency fixture. Issue #1582 asks for -w -D at the workspace root, a test for that case, and unchanged single-project and member commands. The new tests assert those commands, but the fixture writes vitest under dependencies; it sets the finding’s dev flag separately. The prior failure remains unresolved.

Resolution

I recommend declaring vitest under the root importer’s devDependencies and retaining the command assertions. Otherwise, use Refs #1582 until the fixture is complete.

Include the root when it shares a dependency with a member.

If the root and client both declare a vulnerable package, the plan can leave the root vulnerable while counting the finding as covered. This behavior predates the PR, but the new root handling still misses it.

I’d preserve both owners and generate a root -w command as well as the member-filtered command.

Thanks @sarankumar1325, this is ready. I reproduced the failure from #1582: on a pnpm workspace that lists more than one package pattern, main prints pnpm add -D lodash@4.18.1, which fails with ERR_PNPM_ADDING_TO_ROOT, and --fix exits 1. Your branch prints pnpm add -w -D lodash@4.18.1, it succeeds, the rescan is clean, and --fix applies it. Single-project repos and member --filter commands are unchanged, and on analog every root install gains -w with the right attribution. Merged with current main the suite passes and it builds.

One optional extra: the PR body mentions a chain-resolution root target, but nothing tests it. If the || target.workspaceRoot rebuild in fix-commands.ts is removed, the whole suite still passes, and a plan that also has a parent update would then print a bare pnpm add that fails. A test for that case would pin it.

On CodeRabbit's open thread: it's right that when the root and a member both declare the same vulnerable package, only the member's command is printed. Main does the same today, so it's not something this PR introduced; I've filed it as #1592. You can reply with that and resolve the thread.

Approved. I merge these one at a time rather than in a batch, so it will land shortly.

Pins the plan-level rebuild of an explicit chain-resolution command for a
pnpm workspace root target, alongside a parent update in the same plan.

Thanks for adding the chain-resolution root test. It fails if the || target.workspaceRoot rebuild is removed, which was the gap. Re-approving.
