Clears every finding npm audit reports for a clean @percy/cli install (PER-11098: a customer security questionnaire on 1.32.11 showed 12 high and 9 moderate). With this branch packed and installed into an empty project, npm audit reports 0 high and one moderate advisory: fast-xml-parser's XMLBuilder (GHSA-gh4j-gqv2-49f6), which the CLI doesn't call. The fix for it is only in 5.x, and 5.x breaks Node 14 installs (see below).
New in-house PacProxyAgent (adapted from pac-proxy-agent@7, MIT) that fetches the PAC file over http(s), file: and data: only. get-uri and basic-ftp are gone
fast-uri (4 advisories)
@percy/config → ajv → fast-uri
Direct fast-uri ^3.1.9 dependency; lock deduped to 3.1.9. Even ajv 8.20.0 (latest) still allows fast-uri ^3.0.1, so a direct dependency is the only way to force the fixed version
fast-xml-parser
@percy/core
Kept on 4.x, ^4.5.7 (e2d9830). 5.x pulls in xml-naming (node >=16), which breaks yarn install on Node 14. The one remaining 4.x advisory, GHSA-gh4j-gqv2-49f6 (moderate), is in XMLBuilder; the CLI only uses XMLParser (maestro-hierarchy.js)
pdfjs-dist
@percy/core → @percy/cli-pdf
^4.10.38, cherry-picked from #2463 (PDF goldens regenerated). It is now a devDependency: @percy/cli-pdf's build copies the files the browser loads (legacy/build/pdf.mjs, pdf.worker.mjs, standard_fonts, cmaps, LICENSE, 5.4 MB) into dist/pdfjs, so installs no longer get pdfjs-dist's node >=20 engine or @napi-rs/canvas. .yarnrc ignore-engines remains for the Node 14 CI toolchain only
rimraf → glob → inflight (deprecated)
@percy/core
Removed; the browser profile is cleaned up with fs.promises.rm({ recursive, force, maxRetries: 3 }), falling back to fs.promises.rmdir on Node < 14.14
lodash.* etc. via snyk-nodejs-lockfile-parser
@percy/cli-command optionalDependencies
Now an optional peerDependency^2.10.4 (still a devDependency for tests)
Behaviour changes for reviewers
PAC files over ftp: are no longer supported. PERCY_PAC_FILE_URL=ftp://… fails with Unsupported PAC file protocol "ftp:", serve the PAC file over http(s) or from a file instead. http(s), file:, data: and the pac+ prefix work as before.
PAC fetching is hardened: the PAC file request times out after 30s (pacTimeout option) instead of hanging every request; redirects that leave https, or go to anything but http(s), are refused; a bare % in a data: URL (e.g. host.length % 2) is kept. The two copies of pac-agent.js (client, sdk-utils) are checked for parity by a test.
IntelliStory lockfile diffing needs snyk-nodejs-lockfile-parser@^2.10.4 installed by the user (Node >=20.19). Without it, the build takes the full snapshot set via IntelliStoryBailError. This already happened whenever the optional dependency failed to install.
fast-xml-parser stays on 4.x (decided, e2d9830). 5.x pulls in fast-xml-builder → xml-naming@0.3.0 (engines: node >=16), so yarn install (v1) on Node 14 failed without --ignore-engines. With ^4.5.7 it installs cleanly on Node 14. npm audit shows one moderate advisory (GHSA-gh4j-gqv2-49f6, XMLBuilder only, not reachable from the CLI), reported once per dependent @percy/* package.
Pre-existing, not changed here: the build_cjs binary build compiles the async PDF page scripts to regenerator code, so PDF rendering does not work in the standalone pkg binaries (same on master).
Clean npm install on Node 24: fast-xml-parser 4.5.7 → strnum 1.1.2; no fast-xml-builder or xml-naming.
yarn install (v1) on Node 14.18.3 with all 19 tarballs: succeeds without --ignore-engines. This install failed with 5.x.
XMLParser with the maestro-hierarchy options on Node 14 parses a sample hierarchy correctly.
More scenarios (3681b5c) — packed install, Node 14.18.3 and 24.22.0, web project, branch PER-11098-e2e
percy upload --ignore "ignored/**": 2 of 3 images uploaded (54996252 / 54996297). percy snapshot --exclude "/drafts/**": 2 of 3 pages (54996353 / 54996376). 2-page PDF through sdk-utils postPdfSnapshot (54996343 / 54996359).
micromatch (master) vs picomatch (this PR) isMatch: identical on 286 snapshot-name/pattern pairs.
PAC scenarios against the packed client and sdk-utils: 21/21 on Node 24 (incl. the 30s default timeout), 20/20 on Node 14.
Fixed in 3681b5c: in sdk-utils, a PAC URL that can't be loaded made every error log retry the failing agent and log again, until the process ran out of heap (a malformed URL already did this on master). The failure is now cached before logging; spec added.
IntelliStory: without snyk, the lockfile diff throws SNYK_LOCKFILE_PARSER_UNAVAILABLE (Node 14 and 24); with snyk 2.10.5 it diffs correctly on Node 20/24 and npm audit stays at 0. bailOnChanges/untraced picomatch globs behave as expected. Pre-existing, unchanged here: LockfileType.npm only parses v1 lockfiles, so v2/v3 (npm >=7) lockfiles fail to diff.
CI: all checks pass. The Percy regression build has 4 diffs, about 0.1%, on "Interactive States & Custom States". The same snapshot shows the same diffs on other branches (PPLT-6233, PER-8619, chore/node-14-to-20) and in earlier runs of this PR, so it's flaky and needs a human approval.
Unit / CI
New pac-agent.test.js in client and sdk-utils. It covers loading (data/file/http(s), redirects, 304 revalidation, hash reuse), ftp rejection, DIRECT/PROXY/HTTPS/SOCKS failover, CONNECT tunnels for https and websocket, fallbackToDirect, and IPv6. pac-agent.js has 100% coverage on Node 14.
End to end (all 19 packages packed with yarn pack, installed into an empty project with overrides)
npm audit (at 3681b5c, with fast-xml-parser 5): 0 vulnerabilities. With 4.x (e2d9830): 0 high, one moderate (GHSA-gh4j, XMLBuilder). npm ls shows no basic-ftp, get-uri, pac-proxy-agent, micromatch, braces, fast-glob, rimraf, inflight or snyk; fast-uri 3.1.9, pdfjs-dist 4.10.38.
Web, static site through a PAC file:PERCY_PAC_FILE_URL=file://…/proxy.pac percy snapshot ./site. The local proxy logged CONNECT percy.io:443, so API traffic went through the new agent. Chromium downloaded and launched. Build 54948020.
Web, --exclude "/skip-*": 3 of 4 pages snapshotted (picomatch). The percy-browser-* profile count was the same before and after (fs.promises.rm cleanup).
Web, PDF snapshot (/percy/pdf/snapshot, pdfjs-dist 4): 1 page rasterized and uploaded. Build 54948040.
Automate token: build 54948115 created and closed through the client. A real automateScreenshot needs a live BrowserStack Automate session and was not exercised.
micromatch pulls in braces, which customer SCA scans flag (PER-11098).
Percy only ever called micromatch.isMatch, which already delegates to
picomatch, so matching behaviour is unchanged. tinyglobby uses
picomatch + fdir and supports the custom `fs` option the sitemap and
upload paths rely on; `expandDirectories: false` keeps fast-glob's
semantics and `absolute: true` keeps absolute paths for the maestro
lookups. Both libraries support Node >=12, so the Node 14 floor holds.

Walkthrough
The pull request replaces glob and PAC proxy dependencies, updates PDF.js packaging and browser loading, changes profile cleanup and parser packaging, and updates related tests and PDF regression manifests.
The upload command uses tinyglobby instead of fast-glob and disables directory expansion.
Core discovery and snapshot matching packages/core/package.json, packages/core/src/api.js, packages/core/src/maestro-screenshot-file.js, packages/core/src/snapshot.js, packages/core/test/api.test.js
Core sitemap and screenshot discovery use tinyglobby. Snapshot glob matching uses picomatch. Screenshot discovery retains its fallback behavior and scoped search options.
PDF.js module loading
Layer / File(s)
Summary
PDF.js asset packaging and selection packages/cli-pdf/package.json, packages/cli-pdf/scripts/vendor-pdfjs.js, packages/cli-pdf/src/assets.js, packages/cli-pdf/test/assets.test.js
The package uses pdfjs-dist 4.x as a development dependency and vendors selected assets. Asset selection supports the vendored directory and uses .mjs library and worker files.
PDF.js browser loading and rasterization packages/cli-pdf/src/browser-scripts.js, packages/cli-pdf/src/index.js, packages/cli-pdf/test/browser-scripts.test.js, packages/cli-pdf/test/fixtures/pdfjs/pdf.mjs, packages/core/src/pdf-rasterize.js
Browser scripts load pdf.mjs when window.pdfjsLib is absent and use the configured worker filename. PDF rasterization calls the exported loader with the asset origin and library filename.
Local PAC proxy agents
Layer / File(s)
Summary
Client PAC proxy implementation and validation packages/client/package.json, packages/client/src/pac-agent.js, packages/client/src/proxy.js, packages/client/test/unit/*
The client replaces pac-proxy-agent with a local PacProxyAgent. It supports data, file, HTTP, and HTTPS PAC sources, resolver caching, redirects, ordered proxy attempts, direct fallback, and proxy tunneling.
SDK utilities PAC proxy implementation and validation packages/sdk-utils/package.json, packages/sdk-utils/src/*, packages/sdk-utils/test/*
SDK utilities add a local PAC agent and tests for PAC loading, resolver reuse, connection handling, and proxy fallback.
Package and runtime maintenance
Layer / File(s)
Summary
Runtime and package updates .yarnrc, packages/cli-command/*, packages/config/package.json, packages/core/src/browser.js
Yarn ignores engine checks. The Snyk parser becomes an optional peer dependency. Core profile cleanup uses filesystem APIs, and config adds fast-uri.
Test configuration and PDF manifests karma.config.cjs, test/regression/assets/pdfs/expected/*
Karma excludes the PAC agent browser test. Expected PDF timestamps, sizes, and hashes change.

Preserve snapshot names for absolute patterns.
When upload.files contains an absolute pattern, fast-glob returns absolute paths, but tinyglobby returns paths relative to args.dirname. Those paths become snapshotName at Line 116, so existing snapshots get new identities and no longer compare with their baselines. Preserve the prior output format for absolute patterns.

Propagate filesystem errors during discovery.
If a directory is unreadable, tinyglobby’s crawler suppresses the EACCES error and returns partial results. Fast-glob previously rejected that error. The upload can therefore succeed without all requested images. The sitemap call in packages/core/src/api.js Line 423 has the same regression. Use a discovery implementation that propagates non-ENOENT errors. (raw.githubusercontent.com)

tinyglobby imports fs functions as named bindings, so it doesn't see
the test harness's fs mocks unless `fs` is passed in. Absolute patterns
with a Windows drive letter also didn't match, so glob a relative
pattern under `cwd` instead.

…sories
A fresh install of @percy/cli audits with four root advisories (#2461).
This clears the two Percy can fix on its own:
- @percy/cli-pdf: pdfjs-dist ^2.16.105 -> ^4.10.38 (GHSA-wgrm-67xf-hhpq,
arbitrary JS on a malicious PDF; patched in 4.2.67). pdf.js 4 ships only ES
modules, so the rasterizer no longer reads legacy/build/pdf.js and injects it
as a classic script body. The page now imports legacy/build/pdf.mjs from the
loopback asset server (new loadLibrary browser script) and pdf.js spawns
pdf.worker.mjs as a module worker from the same directory. The asset
descriptor exposes libFile/workerFile instead of libPath.
- @percy/core: fast-xml-parser ^4.4.1 -> ^5.11.2 (GHSA-gh4j-gqv2-49f6, XMLBuilder
CDATA/comment injection; patched in 5.7.0). Only XMLParser is used, with
processEntities: false, so the advisory was not reachable, but 4.x can never
clear it.
Left as-is because no fix exists upstream yet: basic-ftp (GHSA-c475-qrg2-pj4r,
patched 6.2.1, but every get-uri release still pins ^5.x) and braces
(GHSA-vfj7-8cjw-p6xm, no patched version published).
Toolchain note: pdfjs-dist 4.10.38 declares engines.node >= 20 and
fast-xml-parser 5.8+ pulls xml-naming (>= 16); pdf.js never runs in Node here,
but yarn enforces engines, so this needs the Node 20 CI upgrade (#2386) to
install on CI. Verified locally under Node 14 with --ignore-engines:
@percy/cli-pdf 45/45 at 100% coverage, core pdf-snapshot 40/40 against a real
Chromium, core maestro-hierarchy 162/162.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
… pdf.js 4
pdf.js 4 anti-aliases image edges and glyphs slightly differently from 2.x, so the byte-for-byte goldens no longer match. Regenerated on the pinned Chromium 143.0.7499.0 for each platform; text-only pages differ by a few hundred pixels at channel delta <= 6, the resume page only on its photo and logo bitmaps. Layout and glyphs are unchanged.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…ftp)
pac-proxy-agent loads the PAC file through get-uri, which depends on
basic-ftp and carries its advisories into every @percy/cli install with no
upstream fix. The new PacProxyAgent (adapted from pac-proxy-agent@7, MIT)
fetches the PAC file itself over http(s), file: and data: only, so get-uri
and basic-ftp drop out of the tree. ftp: PAC URLs now fail with a clear error.
A copy lives in @percy/sdk-utils for the same reasons as proxy.js.
PER-11098
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ptional peer
- @percy/config: depend on fast-uri ^3.1.9 directly so ajv resolves the
patched version (yarn.lock deduped to 3.1.9).
- @percy/core: remove rimraf (and its glob/inflight chain); the browser
profile is removed with fs.promises.rm.
- @percy/cli-command: snyk-nodejs-lockfile-parser moves from
optionalDependencies to an optional peerDependency. It brought lodash.*
and other flagged packages into every install. IntelliStory lockfile
diffing now needs it installed; without it the build takes the full
snapshot set, as it already did when the module failed to load.

…in the test proxy
CodeQL and semgrep flagged patterns in the new PAC agent specs: disabled
certificate validation, a test proxy that requested a URL taken from the
request, a route lookup keyed by req.url, and a PAC script built from a
JSON string. Trust the test certificate through `ca` and use localhost
(the cert's CN), have the proxy answer absolute-form requests itself,
guard the route lookup, and escape the PAC string literal.

Force IPv4 resolution for the shared HTTPS fixture.
If localhost resolves to ::1 first, both the DIRECT TLS test and the tunneled HTTPS test can fail because secureTarget listens only on 127.0.0.1. The DIRECT path calls tls.connect independently of the proxy’s net.connect call. Configure the fixture’s localhost lookup to prefer IPv4 in both test files. Keep the URL as https://localhost:${secureTarget.port}/ so TLS hostname and certificate validation remain covered.

Summary
Clears the npm audit findings in @percy/cli by swapping micromatch/fast-glob for picomatch/tinyglobby, replacing pac-proxy-agent with an in-house PAC agent (drops get-uri/basic-ftp), bumping fast-xml-parser/pdfjs-dist (from #2463), adding fast-uri ^3.1.9, replacing rimraf with fs.promises.rm, and making snyk-nodejs-lockfile-parser an optional peer.

Findings
File:packages/cli-pdf/src/browser-scripts.js:33
Severity: High
Reviewer: code-review
Issue: The script that page.eval serializes into the browser loads pdf.js with a dynamic import(). build_cjs (BABEL_ENV=dev, plain @babel/preset-env) rewrites import() into require(), which does not exist in Chromium. PDF snapshots from the packaged/standalone binary would fail with require is not defined. (Inferred from the babel config; not run.)
Suggestion: Exclude this file from the module transform, or inject the script tag/source without import() (e.g. <script type="module"> added via the DOM). Add a test against the build_cjs output.
File:packages/cli-pdf/package.json:32
Severity: High
Reviewer: code-review
Issue:pdfjs-dist@^4.10.38 declares engines.node >=20. @percy/cli-pdf and @percy/core still declare >=14. Yarn classic enforces transitive engines by default, so yarn add @percy/cli on Node 14–18 aborts. The repo's .yarnrc --ignore-engines only hides this in CI.
Issue: The cherry-pick from PER-11036: fix(deps): clear pdfjs-dist and fast-xml-parser audit advisories #2463 set @percy/logger to 1.32.12-beta.2. Master and the rest of the monorepo use 1.32.13-beta.0. The registry copy gets installed instead of the workspace one, which means a second logger singleton and a lerna version mismatch.
Suggestion: Restore "@percy/logger": "1.32.13-beta.0" and regenerate yarn.lock.
File:packages/client/src/pac-agent.js:265 (and the sdk-utils copy)
Severity: Medium
Reviewer: code-review
Issue:requestPacFile has no timeout. A PAC host that accepts the connection but never responds leaves every API request pending forever.
Suggestion: Add a request timeout (e.g. 30s) and reject with a clear error. Share a single in-flight fetch between requests while the cache is cold.
File:packages/client/src/pac-agent.js:271
Severity: Medium
Reviewer: code-review
Issue: Redirects are followed across schemes, so an https PAC URL can be redirected to plain http.
Suggestion: Reject redirects from https to http.
File:packages/client/src/pac-agent.js:252
Severity: Medium
Reviewer: code-review
Issue:decodeURIComponent on the data-URL body throws URIError on a literal % (e.g. h.length % 2 in a PAC script). The old data-uri-to-buffer path tolerated it.
Suggestion: Decode only valid %XX sequences (e.g. body.replace(/%[0-9A-Fa-f]{2}/g, decodeURIComponent)). Add a test.
File:packages/core/src/browser.js:193
Severity: Medium
Reviewer: code-review
Issue:fs.promises.rm was added in Node 14.14. On Node 14.0–14.13 the call throws before .catch is attached, so browser.close() rejects. rimraf failures used to be logged at debug level only.
Suggestion: Wrap the call in a try block, or fall back to fs.promises.rmdir(dir, { recursive: true }) when rm is missing.
File:packages/cli-command/package.json:34
Severity: Medium
Reviewer: code-review
Issue: snyk-nodejs-lockfile-parser is now an optional peer pinned to exactly 2.10.4. IntelliStory lockfile diffing is silently off unless the user installs it, and installing any other version gives an npm ERESOLVE peer conflict.
Suggestion: Use ^2.10.4, and log at info level (not debug) when lockfile diffing is skipped because the parser is missing.
File:packages/sdk-utils/src/pac-agent.js:1
Severity: Low
Reviewer: code-review
Issue: A 214-line copy of the client PAC agent (and a 340-line copy of its tests), kept in sync only by a comment.
Suggestion: Export it from one package and import it in the other, or move it to a small shared internal package.
File:packages/config/package.json:447
Severity: Low
Reviewer: code-review
Issue:fast-uri is added only to steer hoisting. Nothing makes ajv resolve to that copy under pnpm or with a nested ajv. pdfjs-dist 4 also adds the native optional @napi-rs/canvas to every install.
Suggestion: Bump ajv or use resolutions/overrides instead. Consider whether pdfjs-dist needs to be a runtime dependency at all.
…p bare % in data URLs
- A PAC server that never answers no longer hangs every request: the fetch
times out after 30s (pacTimeout option).
- Redirects may not leave https, or go anywhere but http(s).
- A `%` that does not start an escape in a data: URL is kept, so
`host.length % 2` loads without encoding.

…e 14 floor
pdfjs-dist 4.10 declares node >=20 and pulls in @napi-rs/canvas, but pdf.js
only runs in the discovery browser. The build now copies the files the page
loads into dist/pdfjs and pdfjs-dist becomes a dev dependency; assets.js
prefers the vendored copy and falls back to pdfjs-dist in a source checkout.
Also pins @percy/logger to the monorepo version (1.32.13-beta.0).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- core: fall back to fs.promises.rmdir when fs.promises.rm is missing
(Node < 14.14) so browser profile cleanup still runs.
- cli-command: accept any 2.x snyk-nodejs-lockfile-parser >= 2.10.4.
- client: test that the @percy/sdk-utils copy of pac-agent stays in sync.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The joined paths come from fixed constants and the resolved pdfjs-dist
directory, never from user input. Same inline suppression the repo uses
in core/src/unzip.js and cli-doctor.

Correct the Node version in the installation guidance.
On Node 22.12, this message recommends installing the parser, but Yarn’s engine checks reject version 2.10.4. Its supported Node range is ^20.19.0 || ^22.13.0 || >=24.0.0. State that range in the message. (raw.githubusercontent.com)

Update the installation guidance in the error message assigned to err to state
the parser’s supported Node range as ^20.19.0 || ^22.13.0 || >=24.0.0 instead of
implying all Node versions >=20.19 are supported.

Reject malformed PAC redirect locations instead of crashing.
If a PAC server returns a redirect with an invalid Location, new URL() throws inside the asynchronous response callback. The Promise executor cannot catch that later throw, so the error can terminate the process instead of rejecting getResolver(). Catch the parse error and reject the PAC load. (nodejs.org)

Review comment at @packages/client/src/pac-agent.js at line 62:
In the PAC redirect response callback, handle errors from parsing
`resHeaders.location` with `new URL()` and reject the PAC-loading Promise so
malformed redirect locations do not escape as uncaught asynchronous exceptions
in `getResolver()`.

Start the PAC timeout before connection and carry one deadline through redirects.
req.setTimeout(timeout, ...) measures socket inactivity after connection. DNS or TCP setup can exceed 30 seconds, and continuous response data can prevent the timer from firing. Each redirect also receives a fresh 30-second timeout. Because loadResolver() awaits PAC loading, PAC-dependent requests can remain blocked beyond the intended limit.
Create one wall-clock deadline before get(), pass the remaining time through redirects, and apply the same correction to both PAC-agent copies.

proxyAgentFor logs a failure as an error, and sdk-utils sends error logs to
the CLI through request(), which calls proxyAgentFor again. An agent that
can't be created (a malformed PERCY_PAC_FILE_URL, or now an ftp:// one) was
never cached, so each log retried, failed and logged again until the SDK
process ran out of heap. Cache the failure so later requests go direct.

Include PERCY_PAC_FILE_URL in the cache key.
When PERCY_PAC_FILE_URL changes, the existing ${protocol}//${hostname} key still returns the cached null. The corrected PAC URL is not loaded, and request.fetch sends the request without an agent. Include the PAC URL in the key while preserving the cached null for repeated failures with the same configuration.
Suggested fix
let cache = (proxyAgentFor.cache ||= new Map());
let { protocol, hostname } = new URL(url);
- let cachekey = `${protocol}//${hostname}`;+ const pacUrl = process.env.PERCY_PAC_FILE_URL;+ let cachekey = `${protocol}//${hostname}`;+ if (pacUrl) cachekey += ` via PAC ${pacUrl}`;
// If we already have a cached agent, return it
if (cache.has(cachekey)) {
return cache.get(cachekey);
}

Add a regression test that runs the real logger path.
spyOn(logger, 'log') replaces logger.log with a stub. Jasmine spies do not call the original function unless .and.callThrough() is set. The send-to-CLI branch lives inside logger.log, so this test never reaches it. The new assertions check the cached proxyAgentFor result and the count of error-level calls. They do not show that a logging loop stops.
The existing toBeNull() check still catches removal of the cache. It does not catch a loop that reenters through request. Add a test that does not spy on logger.log. Point PERCY_PAC_FILE_URL at an unsupported PAC URL, start a local endpoint, call proxyAgentFor for that endpoint, and assert that the endpoint receives a bounded number of requests.

fast-xml-parser 5 pulls in fast-xml-builder -> xml-naming, which declares
node >=16, so `yarn install` (v1) on Node 14 fails with an engine error
unless --ignore-engines is passed. Pin ^4.5.7 instead: its one advisory
(GHSA-gh4j-gqv2-49f6) is in XMLBuilder, which the CLI does not use;
maestro-hierarchy only uses XMLParser.
