What does this PR do?

ensureWindowsRestrictiveAcl previously called:

icacls credentials /inheritance:r /grant:r USERNAME:F

/inheritance:r strips all inherited ACEs and leaves the file protected solely by the USERNAME env-var grant. On Windows with Microsoft Accounts or domain-joined machines, USERNAME may not resolve to the same SID that owns the file — the resulting ACL locks out the file owner, causing every subsequent credential read to fail with EPERM: operation not permitted.

Fix: call icacls /reset first (re-enables inheritance from the parent directory), then /grant:r USERNAME:F as an explicit belt-and-suspenders Full Control entry.

Verified on Windows 11 Pro:

  • testsprite setup --from-env --yes + testsprite doctor previously failed immediately with EPERM
  • After this fix, testsprite doctor reports all checks passed ✅

Summary by CodeRabbit

Bug Fixes

  • Improved Windows credential file permissions by resetting inherited access before applying restricted access for the file owner.
  • Added clearer warnings when permission updates fail or do not complete successfully.
  • The diagnostic command now handles unreadable credential files without crashing. It reports a failure with repair guidance when no API key is available, or warns and continues when an API key is set.

Closes #304

Walkthrough

Windows credential ACL handling now resets permissions before granting Full Control to the OWNER RIGHTS SID. The doctor command handles EPERM and EACCES while loading configuration, reports the Credentials check, and passes resolved configuration to its HTTP clients.

Changes

Credential access and diagnostics

Layer / File(s) Summary
Reset and grant ACL permissions
src/lib/credentials.ts, src/lib/credentials.test.ts
Windows ACL handling runs icacls /reset, then grants Full Control with /inheritance:r /grant:r *S-1-3-4:F. Tests cover command order, secure spawn options, spawn errors, non-zero exit statuses, and stderr warnings.
Handle unreadable credentials in doctor
src/commands/doctor.ts, src/commands/doctor.test.ts, src/lib/config.ts
runDoctor falls back to options and environment values when config loading reports EPERM or EACCES. The Credentials check reports a failure when no API key is available and a warning when TESTSPRITE_API_KEY is set. DEFAULT_API_URL is exported for the fallback config.
Pass resolved configuration to doctor clients
src/commands/doctor.ts, src/lib/client-factory.ts, src/commands/doctor.test.ts
Doctor passes its resolved configuration to the Connectivity and Local tunnel checks. The client factory uses supplied configuration without loading the credentials file again.

Merge Risk: 🟡 Moderate · up to b497b

The Windows ACL fix looks sound. However, when the credentials file is unreadable and TESTSPRITE_API_KEY is set, doctor says commands still work and exits successfully, while ordinary commands still fail reading the same file. Users get misleading diagnostics for the exact lockout this PR targets. Either make the environment key bypass the unreadable file in shared config loading, or report the check as failed, before merging.

Thanks for this — the diagnosis is exactly right, and it's a regression we introduced: an earlier Windows ACL hardening change runs icacls <path> /inheritance:r /grant:r %USERNAME%:F with no /reset, so on Microsoft-Account or domain-joined Windows the explicit USERNAME grant may not resolve to the SID that owns the file and the owner gets locked out of their own credentials. /reset before the grant is the right shape.

Your CI had never been approved to run (first-time-contributor gate — our fault, not yours). I've approved it, and now that it has run there's one thing to fix:

  • Lint & Format fails. Run npm run lint:fix && npm run format and commit the result.

Everything else is green, including the Windows leg, which is the one that matters here.

One request while you're in there: please make sure there's a unit test that pins the icacls argument order — the existing spawnSync mock in credentials.test.ts gives you the seam. This code path can only fail on real Windows with a non-local account, so the test is the only thing that will stop the next person from re-introducing /inheritance:r without /reset.

Push those and I'll merge. This is a customer-visible break for Windows users, so it's going out in the next release.

Correcting my own steer from 8/13: "/reset before the grant is the right shape" was true as far as it went, but I said "push those and I'll merge" without checking what /reset + /grant:r actually leaves behind — and it doesn't leave the file restrictive. That gap is mine, not yours. Here's what actually needs to change before I can merge.

What /reset + /grant:r alone does, and why it isn't equivalent to the /inheritance:r it replaces:

  • icacls <path> /reset (credentials.ts:242) clears the "protected" flag and re-enables inheritance from the parent directory. It adds no ACE of its own.
  • icacls <path> /grant:r <user>:F (credentials.ts:248) replaces only <user>'s explicit ACE. It doesn't strip the inherited ACEs /reset just turned back on, and it doesn't restore the protected flag.
  • Net effect: the file is no longer decoupled from its parent directory's ACL — it inherits whatever the parent grants, and will keep tracking any future change to that parent ACL. That's the opposite of what this function's own docstring promises ("Windows hosts use ACL tightening via icacls", credentials.ts:207), and it's now a real asymmetry with the POSIX branch (credentials.ts:216), which still does chmod(0600).
  • On a standard single-user Windows profile this is a modest gap — inherited ACEs there are typically just owner + SYSTEM + Administrators. On a domain-joined or GPO-managed machine it's wider, since inherited ACEs routinely include broader groups there. This is a hardening regression, not a live exploit — but it's exactly the thing ensureWindowsRestrictiveAcl exists to prevent, so I can't take it as-is.

Root cause — not walking this back: your diagnosis is correct. %USERNAME% doesn't reliably resolve to the SID that owns the file on Microsoft-Account or domain-joined machines, so the old /inheritance:r /grant:r %USERNAME%:F could strip every inherited ACE and then grant to a SID nobody has, leaving an ACL nobody can read — exactly the EPERM in #304. /reset first is the right move for unwinding that broken state. It just can't be the last step.

What I need: keep /reset as the cleanup, then re-tighten with a grant target that's guaranteed to resolve. Pick whichever of these — I'll take a working version of any of them:

(a) Grant to the well-known OWNER RIGHTS SID instead of a username. It always resolves and always means "whoever owns this file":

icacls <path> /reset
icacls <path> /inheritance:r /grant:r *S-1-3-4:F

This is closest to what the docstring already claims, and it removes the dependency on USERNAME resolving to anything — which is the actual root cause. My preference, but not a requirement.

(b) Resolve the real owning SID first (e.g. [System.Security.Principal.WindowsIdentity]::GetCurrent().User.Value or whoami /user) and grant to that SID literal instead of the USERNAME string.

(c) Grant first, then /inheritance:r, then read the resulting ACL back and confirm the intended principal has F before returning — rolling back to the inherited state (re-/reset) if the tightening left the file unreadable, instead of leaving it silently broader.

Two more things while you're in there:

  1. The first run('icacls', [path, '/reset'], ...) call (credentials.ts:242) discards its return value — only the second call's result is checked. CodeRabbit flagged exactly this on this PR on 2026-08-03 and it's still open on the current head: if /reset fails, execution falls straight through to the grant with no warning. Check result.error / result.status on both calls the same way.
  2. There's no test for /reset failing, or /reset succeeding while /grant:r fails. The existing "warns on Windows when credentials ACL tightening cannot run" test only covers a missing USERNAME env var, where spawnSync is never called at all — it doesn't exercise the icacls-failure path either call could actually hit.

Separate, factual, not something to fix in this PR: mutateCredentialsFile's mkdirSync(dirname(path), { recursive: true, mode: 0o700 }) (credentials.ts:283) — the mode option is a documented no-op on Windows, so the parent directory was never actually tightened by us on this platform either. Just context for why the file-level ACL is the only real control point here; not blocking.

On CI: your 2026-08-18 push was a pure Prettier reflow, no logic change. Full CI had never actually run on that head — the fork-approval gate re-arms on every push from a first-time contributor, so your checks tab was empty through no fault of yours. I've approved the run now. Two failures in it are ours, not yours: Dependency Review (org-level dependency graph is off org-wide, fails on every PR) and ESLint Security (changed files) (pre-existing lint backlog; the fix ships in our source repo on the next release). Unit Tests (Windows) also failed on the first attempt, but on an unrelated timeout in test.test.ts (runFailureGet > in-place rewrite removes stale top-level files — Test timed out in 5000ms, in a filesystem-heavy test whose sibling took 2562ms on the same runner). Your credentials.test.ts passed clean in that same run (25 passed, 1 skipped, 0 failed), and this PR touches nothing that test reaches. I re-ran the Windows job to be sure rather than asserting it — it passed, so that was a runner-speed flake, not your change. Everything except the two infrastructure checks above is now green.

Push the ACL fix plus the two follow-ups above and I'll take another look.

Hi @zeshi-du, thank you for the exceptionally thorough review — and for owning the gap in the earlier steer. No apology needed at all; your analysis of what /reset + /grant:r leaves behind made the fix straightforward to land.

I went with option (a), since it addresses the root cause directly:

Both follow-ups are also addressed:

  1. Both icacls calls now check result.error and result.status, with distinct warning messages for the /reset and grant phases (the first call previously discarded its result — thanks to CodeRabbit for flagging that originally).
  2. credentials.test.ts now pins the exact argument order of both calls, and adds coverage for all four failure paths: /reset erroring, /reset exiting non-zero, and the grant failing (error / non-zero) after a successful /reset.

I also removed the now-unused env field from RestrictiveModeOptions, since nothing reads %USERNAME% anymore.

Noted on mkdirSync's mode being a no-op on Windows — thanks for the context; happy to look at that separately if it'd be useful.

Apologies for the silence — you pushed the OWNER RIGHTS SID fix on 2026-08-28 and it sat here for over two weeks. That was the exact thing we asked for on 08-19, and it's the right approach: process.env.USERNAME can't be relied on to resolve to the file owner's SID on a Microsoft-account or domain-joined machine, which is what turned the ACL hardening into a lockout in the first place.

Status and what's next:

  • It still merges cleanly against current main (v0.11.0) — I re-checked today, no rebase needed.
  • Your CI has never run. Fork PRs on this repo sit at action_required until a maintainer releases them, and nobody did. That's on us, not on you; it's being unblocked now, and I'll review against a green run.

Two things I expect to raise in that review, flagged early so you can decide whether to fold them in:

  1. Already-affected users aren't recovered. Someone who ran an affected version still has a credentials file carrying an ACL they can't read. Worth either a repair path or, at minimum, a doctor message that says to delete ~/.testsprite/credentials and re-run setup.
  2. The tightening step fails open. If the ACL change fails after the file is created, we continue silently with default inheritance. A stderr warning would make that visible.

Neither is large. Thanks for staying with this one.

CI has finally run on this — that was our fault, the workflow was sitting unapproved for 18 days. Results: everything passes except one real item and one that isn't yours.

Real, and it's a two-minute fix. ESLint Security (changed files) flags six security/detect-non-literal-fs-filename findings in src/lib/credentials.test.ts:

313:5  mkdirSync      329:5  mkdirSync      356:5  mkdirSync
314:5  writeFileSync  330:5  writeFileSync  357:5  writeFileSync

These are test fixtures writing into the suite's own mkdtempSync directory, which is fine — the rule just can't see that. This repo's established convention is an inline disable with a reason, e.g. from src/commands/doctor.tunnel.spec.ts:

// eslint-disable-next-line security/detect-non-literal-fs-filename -- `dir` is this suite's own mkdtempSync temp dir, never user input
mkdirSync(dir, { recursive: true });

Add one of those above each of the six lines and the job goes green. Please don't silence the rule at config level.

Not yours: Dependency Review fails on every PR in this repo because our organisation has the dependency graph disabled. A fix is in flight internally. Ignore it.

Everything else is green, including Unit Tests (Windows) — which is the platform that matters most for this change.

With that and the two review points from my earlier comment (a repair path for already-bricked files, and not failing open silently when the ACL tightening fails), this merges.

Hi @zeshi-du, thanks for unblocking CI and for flagging the review points early — all three items are addressed in the latest push:

1. ESLint Security findings (the six security/detect-non-literal-fs-filename lines)

Added the inline disable with a reason above each of the six calls in src/lib/credentials.test.ts, following the convention from doctor.tunnel.spec.ts — the reason notes the paths are the suite's own mkdtempSync temp dir, never user input. The rule itself is untouched at config level.

2. Recovery for already-affected users

Went with the doctor-message option. testsprite doctor now detects the bricked state directly: when the credentials file exists but the OS refuses the read (EPERM/EACCES — the signature of the locked-out ACL), it no longer dies with a raw fs error. Instead the Credentials check reports:

credentials file exists but cannot be read (EPERM); its ACL may be locked out by an earlier CLI version — delete the file and re-run testsprite setup

If TESTSPRITE_API_KEY is set (commands still work), the check degrades to a warning instead of a failure. Covered by two new tests in doctor.test.ts (fail without env key, warn with it).

3. Tightening must not fail open silently

The current head already checks result.error and result.status on both icacls calls, and every failure path emits a stderr warning via the default warn sink. To pin that contract, credentials.test.ts now has a test that runs with no injected warn callback and asserts the [warning] … line lands on process.stderr — so a future regression to silent fail-open fails CI.

Happy to iterate on any of the above. And noted on Dependency Review — understood that it's org-side and not something I can affect from the PR.

Reuse the fallback configuration for connectivity.

checkConnectivity calls makeHttpClient, which calls loadConfig again. loadConfig reads the credentials file before it applies TESTSPRITE_API_KEY. An unreadable credentials file can therefore abort doctor after the fallback configuration succeeds.

Pass the resolved configuration to the client, or prevent this second credentials-file read.

Hello @aythin, thanks for the latest push, and apologies again on CI.

GitHub builds pull_request runs from the PR's merge commit, and this PR is now conflicted, so there is no merge commit to build from and no check suite gets scheduled. So the rebase is the unblock rather than a trailing cleanup step: once the conflict clears, the runs will be created.

The ACL work is right, and I checked the assumption it rests on rather than taking it. I built this head on Windows 11 and bricked a credentials file the way the bug does, leaving only SYSTEM on the ACE. icacls /reset still succeeds as the owner, so the repair path is genuinely viable. One thing worth a comment in the code: the F in the OWNER RIGHTS grant is load-bearing, not incidental. After /inheritance:r the file carries exactly one ACE, and Full Control is what leaves WRITE_DAC with the owner, which is what makes a later /reset possible at all. If someone "tightens" that to :R, the file becomes unrepairable without taking ownership.

One blocker, in the doctor recovery rather than the ACL. Same machine, real unreadable file. With no env key, your feature works exactly as intended:

[FAIL] Credentials   credentials file exists but cannot be read (EPERM); ... delete the file and re-run `testsprite setup`
[WARN] Connectivity  skipped; no API key to test with

With TESTSPRITE_API_KEY set, which is the case the PR describes as degrading to a warning:

  [WARN] Credentials   ... (TESTSPRITE_API_KEY is set, so commands still work)
  [FAIL] Connectivity  GET /me failed (EPERM: operation not permitted, open '...\.testsprite\credentials')

  1 failure(s), 2 warning(s).

Exit code 1. checkConnectivity calls makeHttpClient, which calls loadConfig with the same credentialsPath, so the file is read a second time and throws the same EPERM. The catch folds it into the generic branch, so a filesystem error surfaces as an API failure and the report contradicts itself.

The tests miss it because loadConfigFn is injected into runDoctor only, and that seam never reaches makeHttpClient. Both new tests also sit outside the writeProfile setup the other tests use, so there's no file at credentialsPath for connectivity to trip over. expect(report.failures).toBe(0) passes for a reason that doesn't hold in production.

Smallest fix in keeping with what you've already done: let the resolved config reach the client, for example an optional pre-resolved config on ClientFactoryDeps that makeHttpClient uses instead of calling loadConfig. Then pin it with a test that drives a real unreadable file. chmod 000 gives EACCES on Linux CI, which the code already accepts, so it works cross-platform.

Rebase, plus the connectivity fix and its test, and I believe this is done. Thanks for staying with it!

The previous icacls call used /inheritance:r which strips all inherited
ACEs and relies solely on the USERNAME env grant. On Windows, USERNAME
may not resolve to the same SID that owns the file (e.g. Microsoft
Account or domain account mismatches), leaving the file unreadable by
anyone including the file owner.

Fix: call icacls /reset first to re-enable inherited permissions from
the parent directory, then add an explicit /grant:r entry as
belt-and-suspenders full-control grant.

Verified on Windows 11 Pro: testsprite doctor passes after fix.

…l error checking

- Replace USERNAME-based grant with /reset followed by
  /inheritance:r /grant:r *S-1-3-4:F (OWNER RIGHTS SID), which always
  resolves to the file owner regardless of Microsoft Account or
  domain-joined username/SID mismatches
- Check result.error and result.status on both icacls calls with distinct
  warnings for the reset and grant phases
- Pin the exact icacls argument order in tests and cover all four
  failure paths (reset error, reset non-zero, grant error, grant non-zero)
- Remove the now-unused env field from RestrictiveModeOptions

…pin stderr warning

- Doctor: when the credentials file exists but the OS refuses the read
  (EPERM/EACCES, the signature of an ACL locked out by an affected CLI
  version), report the repair path (delete the file and re-run setup)
  instead of crashing with a raw fs error; degrades to a warning when
  TESTSPRITE_API_KEY makes commands usable without the file
- Add inline security/detect-non-literal-fs-filename disables with
  reasons on the test fixtures writing into the suite's own mkdtempSync
  temp dir, per repo convention
- Add a test pinning that ACL-tightening failures surface on stderr via
  the default warn sink (no injected warn callback), so a regression to
  silent fail-open fails CI
- Export DEFAULT_API_URL from config.ts for the doctor fallback path

…ials

- ClientFactoryDeps gains an optional pre-resolved config; when present
  makeHttpClient skips its own loadConfig call
- runDoctor passes the resolved config into checkConnectivity and
  checkLocalTunnel, so with an unreadable (ACL-bricked) credentials file
  plus TESTSPRITE_API_KEY neither check re-reads the file and surfaces
  its EPERM/EACCES as a bogus API failure
- Add a POSIX test driving a real chmod-000 credentials file: Credentials
  degrades to a warning and neither Connectivity nor Local tunnel
  mention the fs error
- Comment why :F in the *S-1-3-4:F grant is load-bearing (WRITE_DAC is

Hi @aythin — good catch on the icacls /inheritance:r root cause, that's a solid fix. One gap remains in the new doctor.ts recovery path:

  • When credentials are locked (EPERM/EACCES) but TESTSPRITE_API_KEY is set, runDoctor builds a usable config and reports a Credentials warning — but checkConnectivity → makeHttpClient re-reads the same locked file via loadConfig instead of reusing the config runDoctor already resolved, so connectivity still fails and doctor exits 1 even with a valid env key. Please thread the already-resolved config into the connectivity check instead of re-reading.
  • Please add a regression test for exactly that case (locked file + env key → doctor passes), and rebase doctor.ts against main — it currently conflicts, which is also why real CI hasn't run on this head yet.

Thanks for the detailed root-cause write-up on the ACL issue, that part is solid.

Hi @jangjos-128, thank you for taking the time to test this on a real Windows machine, all addressed:

  • Rebased onto current main — the merge commit exists, so CI should schedule now. Thanks for your patience with the fork-approval friction along the way.
  • Double-read fixed — ClientFactoryDeps accepts an optional pre-resolved config; when present the factory skips its own loadConfig. runDoctor passes its config into both checkConnectivity and checkLocalTunnel — while rebasing I noticed the tunnel check had the same latent double-read, so it's covered too.
  • Real-path test — creates a credentials file, chmod 000s it (EACCES on Linux CI), sets TESTSPRITE_API_KEY, and asserts Credentials reports the warning while neither Connectivity nor Local tunnel mention the fs error; report.failures === 0. Skipped on Windows (chmod is a no-op there); the injected-EPERM tests stay for cross-platform detail coverage.
  • :F comment added — the grant now notes that Full Control is what leaves WRITE_DAC with the owner and keeps a later /reset possible; :R would make the file unrepairable without taking ownership.

Thanks for verifying the /reset repair path on a real bricked file — good to know the recovery story holds where it matters.

Make environment-key recovery work in the shared config path.

readCredentialsFile calls readFileSync without catching EPERM or EACCES. loadConfig performs that read before applying TESTSPRITE_API_KEY. Doctor avoids the failure only because it passes its fallback config to its own checks. Ordinary commands still resolve config without that fallback, so they can fail even when the environment key is set.

checkCredentials reports this state as warn and says that commands still work. Doctor can therefore return zero while subsequent commands fail. Add the environment-key recovery to loadConfig, or report the Credentials check as failed when recovery is unavailable. Extend the test to cover an ordinary command, not only doctor connectivity, and keep the warning text consistent with the selected behavior.

Hi @aythin, thank you for the quick turnaround!

The open change request predates this push — everything it asks for is in b497b33b, so nothing there needs action from you; we'll get the review state refreshed on our side.

I checked b497b33b against the code rather than the commit message and it all holds: runDoctor threads the resolved config into both checkConnectivity and checkLocalTunnel, and client-factory now does deps.config ?? loadConfig(...), so the credentials file is read once. Spotting that the tunnel check had the same latent double-read was a good catch — that one wasn't on the list.

The new chmod 000 test pins the case that matters: on a genuinely unreadable file with TESTSPRITE_API_KEY set, Connectivity and Local tunnel both stay ok and report.failures === 0. It's green on Node 20 and 22, and Unit Tests (Windows) passes as well. The rebase did its job too — CI is scheduling on this head again. And thanks for the :F note in ensureWindowsRestrictiveAcl; that's the detail that keeps the file repairable.

One item left, and it's the only red check — ESLint Security (changed files):

src/commands/doctor.test.ts:331:7  security/detect-non-literal-fs-filename 
Found chmodSync from package "node:fs" with non literal argument at index 0

Same convention you already applied in credentials.test.ts:

  // eslint-disable-next-line security/detect-non-literal-fs-filename -- `credentialsPath` is this suite's own mkdtempSync temp dir, never user input
  chmodSync(credentialsPath, 0o000);

Non-blocking, while you're in there: the new test's expect(out).not.toContain('EACCES: operation not permitted') can never fail — Node renders EACCES as "permission denied"; "operation not permitted" is EPERM's wording. The assertions that carry the weight (connectivity?.status === 'ok', failures === 0) are correct, so it's a dead line rather than a hole.

Push the lint fix and this is ready to merge. Thanks for staying with it through the CI friction — the ACL fix and the recovery path are both solid work.
