Resolved conflicts:
- page.rs: keep both set_blocked_urls (#315) and stealth client wiring
- ops.rs: keep SHA-512/224 + SHA-512/256 from stealth branch; keep
the unreachable catch-all (vec![]) from #314 instead of silent
SHA-256 fallback; updated comment accordingly
- bootstrap.js: extend the digest algorithm allowlist to include
SHA-512/224 and SHA-512/256 to match the Rust additions
The default HTTP path emitted headers with user-agent first and sec-fetch-dest
before sec-fetch-site, an order no real browser produces and a known
fingerprint signal. Reorder the explicit headers to Chrome's top-level
navigation order (sec-ch-ua family, upgrade-insecure-requests, user-agent,
accept, sec-fetch-site/mode/user/dest, accept-language). reqwest still appends
accept-encoding and host after these, so accept-encoding lands after
accept-language instead of before it; the rest matches Chrome exactly.
permissions.query returned "granted" for every permission except notifications.
Real Chrome defaults camera, microphone, geolocation, and midi to "prompt", so
answering "granted" for them is a bot tell. Return "prompt" for those (keeping
notifications in sync with Notification.permission) and "granted" for the rest.
The non-stealth navigation path hardcoded sec-ch-ua-platform "Linux" and a
fixed sec-ch-ua using Chrome 149's GREASE token, regardless of the selected
profile. With the default Windows Chrome 143 profile that meant a Windows UA
and navigator.userAgentData traveling with a Linux sec-ch-ua-platform header
and mismatched brands, a cross-layer inconsistency a site can check at a
glance. Derive both headers from the profile User-Agent using Chromium's
per-major GREASE algorithm, so the HTTP client hints agree with the JS surfaces.
Backspace always trimmed the last character and typing always appended,
ignoring any selection. So "select-all, then Backspace to clear" left
all but one character, and typing over a selection accumulated text
instead of replacing it.
Backspace now deletes the selected range when one is set, and typed
text replaces it, matching the browser. selectionStart is null during
ordinary typing, so the previous append/trim behavior is preserved when
no selection is tracked.
Pairs with the triple-click select-all in #320 to make the common
"triple-click, Backspace, retype" clear pattern work end to end. Also
fixes the same pattern when a page sets the selection via select() or
setSelectionRange().
Passing detail:clickCount to MouseEvent is necessary but not sufficient
for triple-click to select all text. The select-all-on-triple-click is a
browser native behavior that synthetic MouseEvent dispatch doesn't trigger.
Add manual selection after click dispatch: when clickCount >= 3 and the
target is an INPUT or TEXTAREA, set selectionStart=0 and
selectionEnd=value.length.
fetch() and XHR did String(body), so passing a FormData as the request body
sent the literal "[object Object]" and lost the multipart payload along with
its boundary. Servers expecting multipart/form-data replied 400 "Invalid
boundary for multipart/form-data", which is what blocked booking.com: the AWS
WAF challenge POSTs its proof-of-work solution to /mp_verify as FormData, so
the verify always failed and no aws-waf-token was issued. Serialize FormData to
a multipart/form-data body with a generated boundary and set the matching
Content-Type, the way a real browser does; URLSearchParams bodies get
application/x-www-form-urlencoded. XHR.send routes through fetch() so it is
covered too. With this, obscura --stealth renders the real booking.com landing
page the same as headless Chrome.
URL.createObjectURL stored blob content asynchronously (blob.text().then) but
the Worker constructor read __blobStore synchronously, so new Worker(blobURL)
in the same tick raced the store, fell through to fetch(blobURL), and failed
with net::ERR_FAILED. This broke Blob-URL workers including the AWS WAF
challenge proof-of-work worker. Store synchronously from Blob._bytes, which the
obscura Blob materializes in its constructor.
location.reload was a no-op, so challenges that reload after setting a token
cookie never re-fetched. It now navigates like assign/replace.
location.href/assign/replace/reload cleared __virtualUrl immediately, so a
script that set location.href and re-read it saw the old URL until the async
navigation completed; real browsers update location.href synchronously. Preview
the resolved target in __virtualUrl and clear it in __obscura_init once the
navigation completes, so immediate reads match and redirects still win.
op_fetch_url backed JS fetch() and XHR with a plain reqwest/rustls client, so
in stealth mode scripted requests carried a non-browser TLS fingerprint and
none of the Chrome client hints the main navigation sends. Bot managers that
score subresource requests (the AWS WAF challenge verify call, Akamai sensors)
read that as a script and reject it. Add StealthHttpClient::send_single and a
stealth_fetch_all path that op_fetch_url uses when a stealth client is
installed, preserving the redirect, SSRF, and CORS handling so JS-level
requests share the navigation's Chrome TLS fingerprint and sec-ch-ua client
hints. The reqwest path is unchanged for non-stealth. Adds a stealth feature to
obscura-js gated on obscura-net/stealth.
Stealth mode forced a Linux navigator UA and platform but reported Windows
in userAgentData.getHighEntropyValues and served Windows Direct3D11 WebGL
renderers, a combination no real Linux Chrome ever produces and that
cross-layer fingerprint checks flag. Present one consistent Windows Chrome
145 identity instead: the wreq emulation uses Platform::Windows, and the
navigator surfaces read the UA and platform from shared constants so the
HTTP User-Agent header, sec-ch-ua-platform, navigator.userAgent, and
userAgentData all agree. userAgentData brands are now derived from the
Chrome major version via Chromium's GREASE algorithm rather than a single
hardcoded token, and a Linux WebGL renderer pool is added so a Linux UA can
never report a Direct3D11 renderer.
The digest op fell through to SHA-256 for any unrecognized algorithm name,
so SHA-512/224 and SHA-512/256 silently returned a SHA-256 hash. Add the
two FIPS 180-4 truncated variants, which the AWS WAF challenge proof-of-work
(used by booking.com and other CloudFront/WAF sites) requires.
Fixes#314.
Unknown algorithm names (SHA-512/224, MD5, etc.) were silently falling
back to SHA-256, producing wrong bytes with no error. Now throws
DOMException('NotSupportedError') to match Chrome behavior.
Supported: SHA-1, SHA-256, SHA-384, SHA-512.
These three interfaces were missing from the global scope entirely.
Site bundles that reference Plugin as a constructor threw
"ReferenceError: Plugin is not defined".
Added as plain function declarations (same pattern as PluginArray) so
they survive the V8 snapshot. navigator.plugins now returns real Plugin
instances and navigator.mimeTypes returns a real MimeTypeArray with
MimeType instances, so instanceof checks work correctly.
Added Network.setBlockedURLs dispatch handling.
Stores blocked URL patterns on each page.
Applies blocking to page subresources and JS fetch / XHR requests.
Supports wildcard CDP-style patterns like *://*.gstatic.com/*.woff2.
Adds DumpFormat::Cookies that serializes the full browser cookie jar as
pretty-printed JSON after page load. Unlike document.cookie, this captures
HttpOnly cookies inaccessible from JS — useful for extracting session
tokens set by anti-bot challenges.
Bug 1: clickCount parameter was read with underscore prefix and silently
discarded. MouseEvent constructor never received the detail field, so
triple-click (clickCount:3) was always treated as a single click by the
DOM — inputs never selected their full text.
Fix: rename _click_count to click_count, pass it as detail in both
mousedown and click MouseEvent constructors.
Bug 2: page.type() intermittently dropped the last character because
the char handler's quote-escaping order was wrong (single-quote before
backslash), and the V8 event loop wasnt pumped after dispatching the
input event.
Fix: fix escaping order (backslash first, then single-quote), and add
page.settle(50) after the char handler's evaluate to pump the event
loop.
--dump assets only walked static DOM attributes (script[src], img[src], ...),
so resources a page pulled in with fetch() or XHR never showed up (issue #301).
Record each absolute URL requested through op_fetch_url in ObscuraState,
expose it via the runtime and Page, and append those URLs to --dump assets as
type "fetch", deduped against URLs already listed from the DOM.
isTrusted was hardcoded to true for every Event, so new Event('x').isTrusted returned true. Real browsers return false for script-constructed events and true only for user-agent dispatched ones, so this was a trivial bot-detection tell (Closes#303).
Track trusted events in a closure-private WeakSet that page JS cannot read or forge; default isTrusted to false. The CDP input pipeline marks its synthesized mouse/key events trusted via a non-enumerable __obscura_markTrusted helper, so automation clicks stay trusted like real Chrome over CDP while page-built events report false.

automation clicks stay trusted like real Chrome over CDP while page-built

Mark the Event constructor as native so that Event.toString() returns "[native code]" instead of leaking the JavaScript implementation. This closes a stealth fingerprinting vector.
The method was missing, so calling it threw TypeError: ... is not a
function, which broke Vue 3/Nuxt client hydration (issue #297). Back it with
the existing attribute_names op, the same source as the attributes getter, so
the order matches attributes and outerHTML.
hasIframeProxy fix contentWindow now returns null when parentNode === null (iframe never inserted into any tree). The previous attempt used isConnected, which broke getBehemothIframe by returning null for iframes inside the phantom iframe's detached document. That caused PHANTOM_DARKNESS to fall back to self (main window), making all DOM measurement ops run on the main document instead of the isolated iframe body, which corrupted the fingerprint element lookup.
Worker auto-execution Worker constructor now resolves relative URLs against location.href, fetches the script, and auto-runs it. The worker scope exposes WorkerGlobalScope so IS_WORKER_SCOPE resolves correctly in creepjs. All three worker types now complete within the 3s timeout instead of silently timing out.
AudioBuffer + AudioContext AudioBuffer class added to globalThis with getChannelData, copyFromChannel, copyToChannel. AudioContext.createBuffer returns a real instance. AudioContext.addEventListener was a no-op; startRendering now dispatches to stored listeners so the complete event fires.
Crypto Crypto class added to globalThis with randomUUID and getRandomValues on its prototype. Fixes ReferenceError in getPlatformEstimate.
NetworkInformation + ContentIndex NetworkInformation class with downlinkMax on the prototype clears noDownlinkMax. ContentIndex stub on globalThis clears noContentIndex. navigator.connection is now a real NetworkInformation instance.
getElementById / querySelector stale index fix id_index only registers nodes at creation time. When replaceChild(fragment, el) swapped in new nodes their IDs hit .or_insert() and were skipped, leaving the index pointing at the detached original. getElementById now verifies the indexed node is in the live document and falls back to a full attribute-selector scan. query_selector_from falls through to the full scan on both index miss and stale entry instead of returning None early.
matchMedia Handles common queries instead of always returning false. prefers-color-scheme: dark returns true (headless Chrome defaults to light mode, so returning true for light is a bot signal). any-pointer: fine, hover: hover, prefers-reduced-motion: no-preference, min/max-width, and (color) return sensible values.
Fingerprint consistency jsHeapSizeLimit raised to 4294705152 (4 GB, matching 64-bit Chrome). getHighEntropyValues platform corrected from "Linux" to "Windows", platformVersion from "6.1.0" to "10.0.0" to match the Windows NT 10.0 UA string. Canvas: real PNG encoder, arc fill, multiply blend mode. Screen class, performance.now, chrome runtime errors fixed.
Build note deviceMemory and hardwareConcurrency use the high-value pools ([4, 8] GB and [4, 6, 8, 12, 16] cores) only when built with --features stealth.
jsHeapSizeLimit raised to 4294705152 (~4 GB) to match 64-bit Chrome.
Was 2172649472 (~2 GB).
getHighEntropyValues platform corrected to "Windows" and platformVersion
to "10.0.0" to match the Windows NT 10.0 user agent string. Was "Linux"
/ "6.1.0", which mismatched the UA and could be detected.
matchMedia now handles common queries rather than always returning false:
prefers-color-scheme:dark returns true (avoiding prefersLightColor headless
flag — headless Chrome defaults to light so true is a bot signal),
any-pointer:fine, hover:hover, prefers-reduced-motion:no-preference,
min/max-width, and (color) return sensible values.
Result: 0% like-headless, 0% headless, 0% stealth, 33/33 obstacle course.
Note: build must include --features stealth for deviceMemory and
hardwareConcurrency to use the high-value pools ([4,8] and [4,6,8,12,16]).
NetworkInformation class with downlinkMax on its prototype clears
noDownlinkMax from the like-headless flag list. creepjs checks
'downlinkMax' in (window.NetworkInformation?.prototype || {}).
ContentIndex stub on globalThis clears noContentIndex. creepjs checks
'ContentIndex' in window.
navigator.connection is now a real NetworkInformation instance instead
of a plain object literal.
Result: 0% like-headless, 0% headless, 0% stealth on creepjs. 33/33
obstacle course unchanged.
Worker auto-execution: Worker constructor resolves relative URLs against
location.href, fetches the script, and auto-runs it. WorkerGlobalScope is
exposed so IS_WORKER_SCOPE resolves correctly. Worker data (navigator,
locale, timezone) now arrives via postMessage within the 3s timeout.
AudioBuffer class added to globalThis with getChannelData, copyFromChannel,
copyToChannel. AudioContext.createBuffer returns a real AudioBuffer. Fixes
ReferenceError that blocked the audio fingerprint section.
Crypto class added to globalThis with randomUUID and getRandomValues on its
prototype. Fixes ReferenceError in getPlatformEstimate.
AudioContext.addEventListener was a no-op; startRendering only fired
oncomplete. Add _listeners map and dispatch to stored listeners.
getElementById and querySelector('#id') returned null for elements inserted
via replaceChild(documentFragment, el). id_index only registers nodes at
creation time; .or_insert skipped IDs on cloned fragments; None caused
query_selector_from to short-circuit the full scan.
Fix querySelector: fall through to full scan on index miss or stale entry.
Fix getElementById: verify node is in live document; fall back to attribute
selector scan if not.
contentWindow getter: return null when parentNode is null (iframe was never
inserted into any tree). Previously returning null for all disconnected
iframes broke getBehemothIframe, which caused PHANTOM_DARKNESS to fall back
to self (main window) instead of the phantom iframe. That made DOC point to
the main document, so rect and font measurements wrote fragment nodes into
the main body, and the subsequent full-DOM scan in getElementById could not
find fingerprint-data through nested fragments in time.
Limiting the null return to parentNode===null (never inserted) means
getBehemothIframe gets a valid nested contentWindow as expected. creepjs
now reports hasIframeProxy: false and 0% stealth detection.
DocumentFragment constructor: pass nid through when provided.
Range.getBoundingClientRect / getClientRects: return commonAncestor rect.
Upgraded wreq to 6.0.0-rc.29 and wreq-util to 3.0.0-rc.12 to apply the latest Chrome 145 TLS fingerprint (16 cipher suites, proper extension order, ALPS, GREASE).
Introduced __obscura_stealth global to isolate stealth-specific JS behaviors from the standard execution path.
Overrode navigator.userAgentData and getHighEntropyValues() in stealth mode to perfectly match the sec-ch-ua network headers.
Restricted hardwareConcurrency and deviceMemory pools in stealth mode to desktop-realistic values (e.g., minimum 4 cores, 4GB RAM) to eliminate mobile-tier leaks.
Fixed usedJSHeapSize occasionally exceeding totalJSHeapSize.
wreq upgraded to 6.0.0-rc.29 and wreq-util to 3.0.0-rc.12 to apply the
latest Chrome 145 TLS fingerprint (16 cipher suites, proper extension
order, ALPS, GREASE).
__obscura_stealth global variable introduced and passed from Rust to JS,
allowing stealth-specific JS behaviors to run only when the stealth flag
is enabled.
Tightened hardwareConcurrency and deviceMemory pools in stealth mode
to desktop-realistic values (e.g. min 4GB RAM, 4 cores), eliminating
mobile-tier values that leak the spoof.
navigator.userAgentData and getHighEntropyValues() are now overridden
in stealth mode to perfectly match the sec-ch-ua header sent by
wreq_util::Profile::Chrome145.
Fixed usedJSHeapSize sometimes exceeding totalJSHeapSize.
OfflineAudioContext.startRendering() now fires oncomplete asynchronously
(microtask) so callers that set ctx.oncomplete after calling startRendering
(fpCollect pattern) get the callback. The rendered buffer contains a
triangle wave scaled to produce the Chrome Linux audio fingerprint sum
(~124.04). createBuffer() now uses persistent Float32Array channels so
written sample values are read back correctly.
screen is now an instance of a Screen class with native getters on the
prototype. Object.getOwnPropertyDescriptor(Object.getPrototypeOf(screen),
"width").get.toString() now returns the expected native-code format instead
of throwing.
chrome.runtime.connect() and sendMessage() now throw the Chrome error
("Could not establish connection. Receiving end does not exist.") instead
of returning silently, matching what fpCollect records for detailChrome.
performance.now() now advances by 0.1ms per call within the same clock
tick, simulating ~100us timer resolution. Previously it aliased Date.now()
which returns the same integer for all calls in one tick, making
redPill2 = Infinity (serialized as null).
WebSocket constructor now throws SyntaxError for non-ws/wss URLs, matching
Chrome's behavior and populating errorsGenerated correctly.
toDataURL() now encodes the real pixel buffer as a valid PNG using
stored-block DEFLATE, CRC32, and Adler32. The 106-byte stub it replaced
was a static value that any canvas fingerprinter could trivially flag.
fill() rasterizes arc paths from this._path using a distance-check
circle fill, so arc-based canvas tests produce real pixel data.
_setPixel() handles globalCompositeOperation='multiply' so fpCollect's
colored-circle blend test composites correctly.
Canvas dimensions now read from getAttribute('width'/'height') so
explicitly sized canvases (e.g. 400x200) use their declared dimensions
instead of always defaulting to 300x150.
canPlayType was undefined on <audio> and <video> elements. Adds HTMLMediaElement
extending Element with canPlayType returning values that match Chrome 145 on Linux
(probably/maybe/empty per MIME type). HTMLAudioElement and HTMLVideoElement extend
HTMLMediaElement. _elementClassFor routes AUDIO and VIDEO tags to the correct class.
Navigator: adds a global Navigator constructor so typeof Navigator !== 'undefined'.
Links it into the navigator prototype chain (_wdProto = Object.create(Navigator.prototype))
so navigator instanceof Navigator returns true, matching Chrome.
These are two of the signals in server-side fingerprint classifiers (fpCollect et al).
PluginArray: real browsers expose a native PluginArray type. navigator.plugins
was returning a plain Array, so `navigator.plugins instanceof PluginArray` and
`navigator.plugins[0].toString()` (which should return [object Plugin]) were
failing sannysoft-style checks. Adds a PluginArray constructor whose prototype
inherits from Array.prototype, with Symbol.toStringTag='PluginArray'. Each
plugin entry now carries Symbol.toStringTag='Plugin' so Object.prototype.toString
returns [object Plugin].
webdriver: moved the webdriver getter off the navigator instance and onto a
thin prototype so Object.getOwnPropertyDescriptor(navigator, 'webdriver')
returns undefined, matching Chrome where the property lives on Navigator.prototype.
Getter is marked native. sannysoft "WebDriver (New)" now reports "missing (passed)".
navigator.platform returned "Win32" while navigator.userAgent said Linux when
using the stealth client. page.rs now calls set_platform("Linux x86_64", "Linux", "")
alongside set_user_agent when the stealth client is active.
bootstrap.js: pre-declare 71 internal _* globals as enumerable:false before
var runs, so they don't show up in Object.keys(window) on real pages.
deviceandbrowserinfo.com detects CDP by setting Error.prepareStackTrace as a spy, then calling console.log(new Error()). _consoleFn accessed a.stack, which fires prepareStackTrace if set. Fix: save/clear/restore around the .stack access.
NetworkInformation (navigator.connection) and ServiceWorkerContainer (navigator.serviceWorker) are EventTargets in real browsers. React 18 and mobile SPAs call addEventListener on them; the stubs lacked it, so the app bundle crashed with 'addEventListener is not a function' (e.g. goofish.com).
Reject request bodies above 16 MiB with 413 before allocating, stopping an
unauthenticated Content-Length OOM (vec![0u8; len]). Add an optional,
default-off OBSCURA_MCP_ALLOWED_ORIGINS allowlist; unset keeps the permissive
default so issue #175 hosted dashboards are unaffected.
SameSite is case-insensitive per RFC 6265bis but servers send it in any
casing (lax, LAX, Lax). Normalize to title-case at parse time so
downstream comparisons work regardless. Unknown values fall back to Lax
per spec.
Add is_forbidden_ip() (loopback, RFC1918, link-local incl. 169.254.169.254,
broadcast, documentation, 0.0.0.0/::, IPv6 unique-local fc00::/7, IPv4-mapped
IPv6) and SsrfGuardResolver (impl reqwest::dns::Resolve) that resolves and
rejects forbidden addresses at connect time, closing the DNS-rebinding bypass.
Wired into the navigation client and the JS fetch()/XHR path. The
--allow-private-network / OBSCURA_ALLOW_PRIVATE_NETWORK escape hatch is kept.

DDoS-Guard's view.js challenge calls Element.prototype.insertAdjacentText
and dies with 'TypeError: t.insertAdjacentText is not a function', blocking
any DDoS-Guard-protected site (e.g. pikabu.ru). insertAdjacentElement was
missing too. insertAdjacentHTML was already implemented, so this just lifts
the same insertion pattern for Text-node and Element insertion semantics.
Both methods mirror the spec: case-insensitive position keywords, four
insertion points (beforebegin/afterbegin/beforeend/afterend), and
insertAdjacentElement returns the inserted element (or null when
beforebegin/afterend has no parent). Registered with _markNative so
Function.prototype.toString keeps reporting [native code] — consistent
with the existing Element.prototype.insertAdjacentHTML stealth registration.
CDP clients (browser-use and similar) focus an input via DOM.focus before
typing; Input.dispatchKeyEvent then targets document.activeElement. Without a
DOM.focus handler the focus call errored, keystrokes landed on nothing, and the
field stayed empty. Resolve the node and call its JS focus(), which sets
document.activeElement. Completes the type path for DOM-agent frameworks.
CDP DOM-agent frameworks (browser-use and similar) could connect but saw a
blank page: navigation never refreshed their cached target url/title, and their
DOM build aborted with "Unknown domain: DOMSnapshot".
- Emit Target.targetInfoChanged after navigation (both CDP Page.navigate and
JS-initiated) carrying the post-nav url/title. Strict clients refresh a target
only on this event; it also fixes Puppeteer/Playwright page.url() tracking.
- Implement DOMSnapshot.captureSnapshot, built from the DOM with synthetic
geometry (no paint engine) and plausible computed styles, keyed by the same
backendNodeId as DOM.getDocument. Enough for tag/ARIA/accessibility element
detection; it runs only when a client requests it, so the fetch path is
unaffected. Coordinate clicking still requires a real layout engine.
* fix(js): serialize dynamic module imports + re-land base href for SPA lazy chunks (#246)
Add a serialized import queue (__dynScriptQueue + __processDynScriptQueue)
in bootstrap.js so that dynamically inserted <script module> tags execute
one at a time rather than concurrently. This prevents re-entrant RefCell
panics in deno_core's futures_unordered_driver when SPAs (Angular, etc.)
append multiple lazy chunks at once.
Also re-land dynamic import <base href> resolution (previously reverted
as 88af239). The original panic was caused by concurrency, not the URL
resolution logic — now safe because imports are serialized.
Inline module scripts also route through the same queue for consistency.
Fixes#246Closes#242 (dynamic import base href)
* Fix base-href resolution, queue wedge, and double-fired load event
- Resolve <base href> to an absolute URL before resolving the script src, and
guard the new URL() call. A path-only base like <base href="/"> (the standard
Angular form) was passed raw to new URL(src, base), which threw "Invalid URL"
out of appendChild and broke the SPAs this change targets.
- Wrap the dynamic-script queue drain in try/finally so __dynScriptBusy is always
cleared. An unexpected throw used to wedge the queue and silently block every
later dynamic script on the page.
- Fire load/error through dispatchEvent only. dispatchEvent already invokes the
element's onload property handler, so the extra explicit onload() call
double-fired it. This also drops the stale enqueue-time callback snapshot and
reads handlers live off the element.

* fix(js): implement CSS.supports() feature detection
CSS.supports() was a stub that always returned false. Sites that
feature-detect CSS support (e.g. CSS.supports('display','flex'))
treated the engine as lacking flexbox and redirected to their
"unsupported browser" page, so the SPA never rendered.
Implement both call signatures — supports(property, value) and
supports(conditionText) — and return true for well-formed standard
CSS declarations, matching modern browser behaviour. Malformed input
(empty property/value, or a condition string with no colon) returns
false.
* Revert CSS.escape change, keep PR scoped to CSS.supports
The escape stub was switched to String(s), which is unrelated to the
feature-detection fix and still not a spec CSS.escape. Restore the original
stub so this PR only touches CSS.supports.
