fix(ui,scraping): a crafted icon executed at import, and a session cookie went to the wrong host - #152
Conversation
…okie went to the wrong host
Two proven security defects from a five-agent sweep, plus the accessibility set
that shipped alongside them.
RCE, proven exploitable. `build-icons.ts` interpolated attribute values from a
NETWORK-FETCHED `icon-nodes.json` into generated TypeScript as `'${value}'`,
unescaped. The validator checked tag names, attribute NAMES and `fill` — never
the value of `d`, `points` or `cx`. A value that closes the string, the object
and the array element and reopens all three yields a glyph module that runs
arbitrary code in every app importing that icon. The regression test transpiles
and EVALUATES the emitted module; the payload set a global before the fix and
does not after. `icon-glyph.ts` already stated the principle — "data reaching an
attribute sink unchecked is how `onload=` gets into the DOM" — and this was a
code sink, which is worse. The 1767 committed glyphs are deliberately NOT
regenerated: that would bury the fix in noise.
A session cookie was sent to any host whose name merely ENDS WITH the cookie's
domain. A host-only cookie for `bank.test` reached `evilbank.test` and
`sub.bank.test` — proven both ways. The CDP jar is every domain the session ever
touched, so an SSO hop's cookies rode along. Scoping is now one function
implementing RFC 6265 §5.1.3 and §5.1.4 — domain and path, both boundaries,
failing closed on an unparseable URL, and a `secure` cookie no longer reaches an
`http:` URL. Path scoping was a third leak the audit had not named: the type
already carried `path` and nothing read it.
Two tenants shared one authenticated session. A declared `auth.key` replaced the
whole session key instead of discriminating within the tenant, so `orgOf(ctx)`
was never consulted and the value was never sanitised. `sessionKeyFor`'s third
parameter is named `discriminator` and had no caller anywhere; it does now.
Keyboard groups were unusable in three ways. A disabled item made everything past
it unreachable — a disabled control cannot take focus, so the reducer returned its
index forever — and if the disabled item was first, nothing in the group was
tabbable at all. A Toolbar stole arrow keys from a text field inside it, which is
its own documented use. `ToastRegion` was not a live region, which is exactly the
failure its own header says the region/child split prevents.
Deliberately NOT done: Toolbar's docs promised one Tab stop, and implementing it
would be strictly worse than the bug — once a text field keeps its own arrows, a
single stop TRAPS, and every button past the field becomes unreachable. The claim
was deleted instead. `SessionSnapshot.headers` is dead on the only production
driver and stays dead: reading headers off CDP would persist a cookie or an
authorization into the session record, which `http.ts` then spreads onto every
allowed host — a wider leak than the dead field. The divergence is pinned instead.

Inline comments:
In `@packages/scraping/src/cdp-target.ts`:
- Around line 105-123: Update the CDP request and console payload handling in
cdp-target.ts so method, type, and text accessors are invoked with their owning
payload as receiver, preserving request.continue() and request.abort() behavior.
In packages/scraping/src/cdp-target.test.ts at lines 132-138 and 173-175, make
the fake accessors receiver-dependent so the tests verify this behavior.
In `@packages/scraping/src/cookie-scope.ts`:
- Around line 80-83: Update cookieHeaderFor to sort the cookies returned by
cookiesForUrl by descending path length before mapping them into the Cookie
header, while preserving the existing formatting and undefined behavior. Add a
regression test covering duplicate cookie names at “/” and “/admin” to verify
the more-specific path is serialized first.
In `@packages/scraping/src/driver-cdp.test.ts`:
- Around line 31-41: Update the CDP fake methods setRequestInterception,
newPage, and setCookie to reject using the repository’s coded UltimateError
fixture or existing error factory instead of bare Error instances. Preserve each
simulated failure message while providing the required stable code, cause, and
executable fix fields.
In `@packages/scraping/src/error-throws.ts`:
- Around line 23-25: Update the missing-browser-driver message in the scrape
error cause to remove the extra colon before the semicolon, so it ends with
“declares no driver;” while preserving the rest of the diagnostic and
installed-driver details.
In `@packages/scraping/src/expect.ts`:
- Around line 98-102: Require history whenever expect.maxDrop is configured,
either by rejecting the combination during definition validation or enforcing
history in the input type; ensure the validation error includes a stable
X_SCREAMING_SNAKE code, cause, and executable fix. Add a regression test
covering maxDrop without history, using the relevant YieldGuardInput validation
and expect definition symbols.
In `@packages/ui/README.md`:
- Line 64: Add an “As of 2026-08” marker to the README’s documented public
behavior claims, including the Toolbar keyboard behavior and the related
live-region and X_UI_INVALID_VALUE contracts at the referenced sections.
In `@packages/ui/src/a11y.ts`:
- Around line 85-88: Update the fallback handling in activate so the trap root
is programmatically focusable before root.focus() runs, including plain div
roots used by Menu and Popover; set or require tabindex="-1" on the root and add
a regression test covering an empty non-focusable div.
In `@packages/ui/src/components/file-input-view.ts`:
- Around line 103-127: Add adjacent file-input-view.test.ts coverage for
adoptDroppedFiles: verify a non-empty dropped FileList is assigned to
input.files, and verify undefined, null, and empty drops leave an existing
input.files value unchanged. Use structural FileTarget test doubles without
requiring DOM APIs.
In `@packages/ui/src/icons/build-icons.test.ts`:
- Around line 18-27: Update the caught test helper’s no-throw path to use the
repository’s established test-failure assertion pattern or a contract-compliant
UiError instead of throwing a bare Error, while preserving the existing behavior
when run() throws and the returned error fields are inspected.
In `@packages/ui/src/icons/build-icons.ts`:
- Around line 33-35: Update the invalidIconDataError fix at
packages/ui/src/icons/build-icons.ts lines 33-35 to contain only the runnable
icon regeneration command, moving URL-check guidance into cause. Apply the same
runnable remediation command required for the version-bump errors at lines 67-70
and 80-83; each fix must be executable verbatim, with no prose.
In `@packages/ui/src/jsx-probe.ts`:
- Around line 33-40: Update probe() and unprobe() to save the existing
globalThis.React property descriptor before the first installation and restore
that descriptor after the final probe is removed, rather than unconditionally
deleting React. Preserve the installed { createElement: h } behavior while
probes are active, and handle repeated or nested probe usage so restoration
occurs only after the matching final unprobe().
- Around line 76-97: Update one, attachRef, and fire to throw UiError or the
established error factory from errors.ts instead of bare Error, assigning each
failure a stable X_* code, a cause, and an executable fix while preserving their
existing validation behavior and messages.
In `@packages/ui/src/roving.test.ts`:
- Around line 1-2: Add a 1–4 line responsibility header before the imports in
the test module containing handlesOwnArrowKeys and tabStopIndex, explaining why
this renderer-free test module exists rather than describing what it contains.

Order the Cookie header by descending path length.
Lines 80-83 preserve jar order. RFC cookie selection requires the more-specific path first. A / cookie can otherwise precede an /admin cookie with the same name, and a server can select the wrong session.
Add a regression case with duplicate names at / and /admin.
Proposed fix

Require history when expect.maxDrop is configured.
YieldGuardInput.history is optional. With expect.maxDrop set and no history, Lines 105-114 pass an empty history to yieldProblem, never record a run, and maxDrop never fires. The comment's “a delay, not a hole” claim is false for this reachable configuration.
Reject this configuration during definition validation, or make history required when maxDrop is set. Add a regression test for the no-history case. As per coding guidelines, every validation error must use a stable X_SCREAMING_SNAKE code, a cause, and an executable fix.

…not take focus Review round on #152. Nine of CodeRabbit's thirteen comments applied, three declined, one deferred to #154. Two were real defects in this PR's own fixes: - `createFocusTrap`'s fallback called `root.focus()`, and a plain `<div>` is not programmatically focusable. Menu and Popover — the two consumers this PR just wired — pass exactly that, so the fallback silently did nothing and focus stayed outside the trap, which is what the fallback exists to prevent. The root now gets `tabindex="-1"` (not `0`, so it never becomes a Tab stop) before being focused. The regression test could not have failed either: the fake DOM granted focus to any element, so the harness now models real focusability. - CDP accessors were invoked without their owning payload as receiver, so a driver whose `method()`/`type()`/`text()` reads `this` got `undefined`. The existing fakes closed over locals and passed either way; they are now receiver-dependent, which is what makes the test a test. Also: the Cookie header was not ordered per RFC 6265 §5.4 — two cookies of one name at `/` and `/admin` serialised in jar order, so a server reading the first occurrence could see the less specific one; probe()/unprobe() clobbered a pre-existing `globalThis.React` and restored nothing on nested use; `adoptDroppedFiles` — the whole of the Dropzone fix — had no test; the icon generator's three `fix:` lines mixed prose into the command, against axiom 4. Declined: three comments asking to replace bare `Error`s in test doubles with coded UltimateErrors. Each fixture simulates third-party or app-supplied code failing, and the property under test is that an ARBITRARY throw is survivable — a coded fixture would stop covering the case that motivated the fix. #132 records the rule as deliberately unenforced in test files. Found while acting on the review, and filed rather than fixed: `scanFixes` resolves a fix-helper's arguments only when the helper is declared in the same file, so every `fix:` passed to a per-package `errors.ts` factory is unchecked (#157). That is the second hole in that scanner this sweep found. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

… for a whole file (#158) * fix(cli,ai,mcp): an apostrophe in JSX text turned the errors gate off for a whole file Second half of the tier-4/5 sweep, split from #152 at ~60 files each. The gate hole was LIVE, not latent. `maskLiterals` treated `'` as a string opener, so an apostrophe in JSX text blanked everything up to the next quote and `scanFixes` returned nothing for the rest of the file — while `scanCodes` kept passing, masking it. `packages/http/src/errors.ts` contains `…already route "${input.otherRoute}"'s`, so EIGHT real `fix:` lines in that file had never been checked by `x verify`. All eight pass now. One test asserted "nothing in the installed framework raises X_DRAINING" — disproved by `draining()` in the very file the gate had stopped reading. The chosen fix is the cheap one — a quote with no partner on its own line is text, copying `endOfRegex`'s existing rule — and its gap is stated rather than hidden: two apostrophes on one line still blank the span between them. Blast radius drops from rest-of-file to one line. Full coverage needs a JSX tokenizer, which the file's own header rules out. `agent()` sent Anthropic a transcript it rejects, in TWO places. A turn emitting a tool call and `respond` together replayed the `respond` tool_use with no matching tool_result. The repair path had the same hole and is far more reachable: ANY output-schema mismatch in an agent() run was a 400. The loop now answers the superseded `respond` with an is_error result telling the model to read the tool results and answer again — rather than discarding a block the model emitted, or using an answer composed before the tools it called had run. MCP's `additionalProperties: false` accepted and dropped every argument named after an Object.prototype member. Third instance of the class this release, and `Object.hasOwn` alone was NOT sufficient — it turns the `__proto__` drop into a `__proto__` re-prototype of the record the handler reads, so every write goes through Object.defineProperty. A page with zero executable JavaScript could fail its JS budget, with a fix line naming an import that does not exist. `x verify --workers 5000` was accepted although both summaries say max 8 — 842 concurrent Bun processes, each with the module graph and a cloned database. Plus seven more instances of the caught-value totality class in ai and mcp, and the smaller CLI set: dev-traces dropping every request that arrived with an inbound traceparent, a bare Error on a taken metrics port, METRICS_PORT ignored in dev, a missing binary whose fix line checks nothing about missing binaries, JSONC in a root tsconfig silently disabling X_PACKAGE_UNREFERENCED. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(cli): the port-collision test asserted the kernel's behaviour, not this package's CI caught a test I added in this PR. `metrics-endpoint.test.ts` bound a live port a second time and expected `Bun.serve` to throw EADDRINUSE. It does locally. GitHub's runner allowed the second bind, so the test failed for a reason that was never this package's contract — a flaky test in the gate is worse than no test. Rewritten to assert the MAPPING, which is what is actually ours: an EADDRINUSE-shaped throw becomes a coded refusal naming the port and the knob that moves it. Whether the OS refuses a rebind is decided elsewhere and does not answer the same way everywhere. `isAddressInUse` was also an instance of the class this whole sweep has been fixing: `error instanceof Error && error.code === 'EADDRINUSE'` runs `getPrototypeOf` and then a getter on a value this process did not build. It reads through core's `stringField` now, which also makes it answer correctly for a bind failure that crossed a worker or a subprocess — a plain object carrying the libc code, for which `instanceof Error` is false. That case is the one the mutation check bites on. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(cli,render): a charset parameter downgraded the JSON escaper, and a fix line named port 65536 Review round on #158. Four of CodeRabbit's seven applied, three declined, plus one finding the review surfaced in a package it did not name. The best catch is a bug I wrote in this very PR. `cmd-doctor` emitted `fix: x dev --port 65536` for `--port 65535`, and this PR added `neighbouringPort` to close it — then `metrics-endpoint.ts` shipped `METRICS_PORT=${port + 1}`, the identical off-by-one, in new code. `neighbouringPort` moved to `flag-number.ts` beside `PORT_RANGE`, the constant that bounds it, and both call it now. `carriesJson` tested whether the type attribute ends in `json`, so a real document's `application/ld+json; charset=utf-8` did not match. In `budgets.ts` that counted an SEO structured-data block as executable JavaScript again — the bug this PR exists to fix, still reachable through the spelling every real document uses. The same predicate exists in `@ultimat3/render`, where it chooses the ESCAPER, and the review did not name that copy. There a charset parameter sent the JSON-LD block — built from route data, which is the path attacker text takes — to `escapeRawTextContent` instead of `escapeJsonContent`. Not a break-out: `</` is escaped either way. But the JSON rule is total on purpose (`<`, `>`, `&`, U+2028, U+2029) so nothing survives that could spell `</script` after any transformation, and a charset is not a reason to leave it. Both copies now cut the MIME parameter first. Also: `exec.ts`'s missing-binary fix interpolated the program name into a shell line unquoted, so a name with a space produced a `fix:` that does not run — it uses the `quoteArg` the repo already ships, moved to a leaf module because `exec.ts` importing `test-shards.ts` would have closed a cycle onto the CLI's one subprocess boundary. And `x verify`'s flag summary promised `min 2` while its reader accepted 1. Declined: moving `MetricsPortInUseError` into `errors.ts` (489 lines; the class puts it at ~504, over the ceiling `filesize` enforces — `db-seed.ts` is the precedent and CLAUDE.md records the exception), replacing hostile-value test fixtures with coded errors (their purpose is to be values the framework did not build), and rendering an MCP result string through `t()` (`packages/mcp` has no `t()` in source, and `from-action.ts:45` states why: it would make a published artifact locale-dependent).

Security half of the tier-4/5 slice, on top of #147 and #148. Two proven security defects, plus the accessibility set that lives in the same files.
bun run verifygreen standing alone (14/17, 3 intentionally skipped); reference-app ratchet unchanged.Split from the CLI/transport half at 61 files each — the full slice was 122, over the review-size guidance.
★ RCE, proven exploitable
packages/ui/src/icons/build-icons.tsemitted${key}: '${value}', wherevaluecomes fromicon-nodes.jsonfetched over the network.iconElementsvalidates tag names, attribute names, and thefillvalue — never the value ofd,points,cx.A value that closes the string, the object and the array element and reopens all three produces a glyph module that runs arbitrary code at import, in every app that imports that icon.
The regression test does not assert on a substring — it transpiles and evaluates the generated module. Before the fix, the payload set
globalThis.__uiIconPwned. After it, the value round-trips as data.JSON.stringifyis the fix. ASAFE_ATTR_VALUEallowlist is defence in depth, added only because the agent could show it refuses nothing: the character set across all 1767 committed glyphs is" ,-.0123456789ACHLMQSVZacehlmnoqrstuvz", and a test asserts the whole committed set passes.src/icons/glyphs/is deliberately not regenerated — 1767 files would bury the one line that matters.The sibling file already stated the principle (
icon-glyph.ts:18-19): "data reaching an attribute sink unchecked is howonload=gets into the DOM." This was a code sink.★ A session cookie sent to the wrong host
Proven with
httpOverFetch: a host-only cookie{name:'sid', value:'SECRET', domain:'bank.test'}was sent verbatim tohttps://evilbank.test/aandhttps://sub.bank.test/a.The match was
host.endsWith(cookie.domain)— no dot boundary in either direction. And the CDP jar isbrowser.cookies(), i.e. every domain the session ever touched, so an SSO hop's cookies ride along.Cookie scoping is now one function (
cookie-scope.ts) implementing RFC 6265 §5.1.3 and §5.1.4 — domain and path, both boundaries — failing closed on an unparseable URL, matchinghostDecision's existing rule rather than inventing a second one. Asecurecookie no longer reaches anhttp:URL (loopback excepted, as browsers do).Path scoping was a third leak the audit never named. My brief asserted
ScrapeCookiecarries nopathfield; it does (target.ts:52), and nothing read it.hostOnlywas not added: CDP'sNetwork.Cookiehas no such field, so the leading dot is the only signal available, and adding a field no driver can fill would repeat theSessionSnapshot.headersmistake below.★ Two tenants sharing one authenticated session
A declared
auth.keyreplaced the whole session key instead of discriminating within the tenant — soorgOf(ctx)was never consulted, and the value was never sanitised (sessionKeyForstrips[^a-zA-Z0-9._-]; that path did not).The corroboration:
sessionKeyFor's third parameter is literally nameddiscriminatorand had no caller anywhere in the repo. It does now. Pinned with two tenants sharing oneauth.key, and with../../etc/passwd\0as a discriminator.Keyboard groups

Reading headers off CDP means capturing observed request headers, which persists acookie/authorizationinto the session record — andhttp.tsspreadssession.headersonto every allowed host. That is a wider leak than the dead field. Deleting the field breaks a shipped interface in an already-cut 2.0.0. The divergence is pinned indriver-parity.test.tsinstead, so it cannot change silently.expect/historyinteraction is pinned deliberately by an existing test by name, and the claim thatmaxDropcould never fire is disproved byguardYielditself — the alarm arms afterMIN_BASELINE_RUNS. Recording unchecked runs would make a stretch of silent zero-row runs the median a latermaxDropmeasures against.bun test, a*.module.scssimport resolves to the file path string, so everystyles['x']isundefinedandcxdrops it — which is exactly why a dead class name survived inField.tsx.

One Biome suppression:
lint/a11y/useAriaPropsForRoleonSwitch, with a five-line reason. The rule reads ARIA alone; native checkedness supplies the state, and the explicit attribute is what froze it on the no-JS path. That is the one place a lint rule was traded for a spec argument — worth a second opinion.Two new test-only modules (
