DOMPurify: CUSTOM_ELEMENT_HANDLING bypasses afterSanitizeElements for allowed custom elements.

GHSA-c2j3-45gr-mqc4

More information

Details

Summary

There is a possible hook-policy inconsistency in DOMPurify 3.4.11 involving CUSTOM_ELEMENT_HANDLING.

When a custom element is allowed via CUSTOM_ELEMENT_HANDLING.tagNameCheck, it appears that the element does not go through afterSanitizeElements in the same way as a normal element. As a result, an application that relies on afterSanitizeElements as a security policy layer to strip sensitive attributes from all elements may see those attributes removed from normal elements but preserved on allowed custom elements.

This does not appear to be a direct DOMPurify XSS or a case where DOMPurify directly allows executable payloads. The preserved value is still inert at sanitize time. The issue becomes relevant when the allowed custom element later re-injects that attribute value into an HTML sink such as innerHTML, creating a second-order XSS gadget.

Details

The issue appears to originate from the control flow in src/purify.ts: line 1672~1691

const _sanitizeDisallowedNode = function (
    currentNode: any,
    tagName: string
  ): boolean {
    /* Check if we have a custom element to handle */
    if (!FORBID_TAGS[tagName] && _isBasicCustomElement(tagName)) {
      if (
        CUSTOM_ELEMENT_HANDLING.tagNameCheck instanceof RegExp &&
        regExpTest(CUSTOM_ELEMENT_HANDLING.tagNameCheck, tagName)
      ) {
        return false;
      }

      if (
        CUSTOM_ELEMENT_HANDLING.tagNameCheck instanceof Function &&
        CUSTOM_ELEMENT_HANDLING.tagNameCheck(tagName)
      ) {
        return false;
      }
    }

CUSTOM_ELEMENT_HANDLING is parsed from user configuration at src/purify.ts: line 741~748

const customElementHandling =
      objectHasOwnProperty(cfg, 'CUSTOM_ELEMENT_HANDLING') &&
      cfg.CUSTOM_ELEMENT_HANDLING &&
      typeof cfg.CUSTOM_ELEMENT_HANDLING === 'object'
        ? clone(cfg.CUSTOM_ELEMENT_HANDLING)
        : create(null);

    CUSTOM_ELEMENT_HANDLING = create(null);

In particular, tagNameCheck, attributeNameCheck, and allowCustomizedBuiltInElements are copied into the internal CUSTOM_ELEMENT_HANDLING object there.

During element sanitization, _sanitizeElements() checks whether a node is forbidden or not allowlisted at src/purify.ts: line 1805~1814

/* Remove element if anything forbids its presence */
    if (
      FORBID_TAGS[tagName] ||
      (!(
        EXTRA_ELEMENT_HANDLING.tagCheck instanceof Function &&
        EXTRA_ELEMENT_HANDLING.tagCheck(tagName)
      ) &&
        !ALLOWED_TAGS[tagName])
    ) {
      return _sanitizeDisallowedNode(currentNode, tagName);
    }

If so, it immediately delegates to _sanitizeDisallowedNode(currentNode, tagName) and returns its boolean result.

Inside _sanitizeDisallowedNode(), the custom-element-specific allow path is implemented at src/purify.ts: line 1672~1692

const _sanitizeDisallowedNode = function (
    currentNode: any,
    tagName: string
  ): boolean {
    /* Check if we have a custom element to handle */
    if (!FORBID_TAGS[tagName] && _isBasicCustomElement(tagName)) {
      if (
        CUSTOM_ELEMENT_HANDLING.tagNameCheck instanceof RegExp &&
        regExpTest(CUSTOM_ELEMENT_HANDLING.tagNameCheck, tagName)
      ) {
        return false;
      }

      if (
        CUSTOM_ELEMENT_HANDLING.tagNameCheck instanceof Function &&
        CUSTOM_ELEMENT_HANDLING.tagNameCheck(tagName)
      ) {
        return false;
      }
    }

If the node is treated as a basic custom element and CUSTOM_ELEMENT_HANDLING.tagNameCheck matches, the function returns false immediately at line 1682 or 1689, meaning “do not remove this node”.

That early return false is significant because control returns directly to _sanitizeElements() via the return _sanitizeDisallowedNode(...) at line 1813. As a result, the later logic in _sanitizeElements() is skipped for that custom element instance, including:

• the namespace validation at src/purify.ts: line 1816~1826

* Check whether element has a valid namespace.
       Realm-safe check (GHSA-hpcv-96wg-7vj8): use the cached Node.prototype
       nodeType getter rather than `instanceof Element`, which is realm-
       bound and short-circuits to false for any node minted in a different
       realm — letting a foreign-realm element with a forbidden namespace
       slip past the namespace check entirely. */
    const nt = getNodeType ? getNodeType(currentNode) : currentNode.nodeType;
    if (nt === NODE_TYPE.element && !_checkValidNamespace(currentNode)) {
      _forceRemove(currentNode);
      return true;
    }

• the fallback-tag mXSS check at src/purify.ts: line 1828~1837

/* Make sure that older browsers don't get fallback-tag mXSS */
    if (
      (tagName === 'noscript' ||
        tagName === 'noembed' ||
        tagName === 'noframes') &&
      regExpTest(EXPRESSIONS.FALLBACK_TAG_CLOSE, currentNode.innerHTML)
    ) {
      _forceRemove(currentNode);
      return true;
    }

• most importantly for this report, the afterSanitizeElements hook dispatch at src/purify.ts: line 1850~1851.

   /* Execute a hook if present */
    _executeHooks(hooks.afterSanitizeElements, currentNode, null);

In other words, a normal allowlisted element continues through _sanitizeElements() and reaches hooks.afterSanitizeElements, but a disallowed-by-default element that is revived by the CUSTOM_ELEMENT_HANDLING.tagNameCheck path does not. This creates a policy inconsistency: an application that relies on afterSanitizeElements to remove an attribute from all elements will observe that the policy is applied to normal elements but not to custom elements allowed through CUSTOM_ELEMENT_HANDLING.

In the PoC, the application hook removes data-bio from ordinary elements, but the same attribute remains on <x-bio> because the custom-element keep path bypasses afterSanitizeElements. The attribute itself is inert at sanitize time and DOMPurify is not directly allowing executable SVG/HTML through. The security impact appears when the application-defined custom element later reads the preserved data-bio value in connectedCallback() and writes it to innerHTML, turning the preserved attribute into a second-order XSS gadget.

PoC

Reproduced on DOMPurify 3.4.11.

Steps

1. Save the following HTML to a file, for example poc.html.
2. Open it in a browser.
3. Observe that the div control loses data-bio, while the allowed custom element keeps it.
4. Observe that after connectedCallback() runs, the candidate payload is reinserted into the DOM and executes through the custom element’s own sink.

This is output of HTML PoC.

Impact

This does not appear to affect DOMPurify’s default configuration as a direct sanitizer bypass.

The impact is limited to applications that:

• enable CUSTOM_ELEMENT_HANDLING,
• rely on afterSanitizeElements as a security policy layer,
• expect that hook to apply uniformly to all surviving elements,
• and have allowed custom elements that later re-inject preserved attribute values into innerHTML or another HTML sink.

In that situation, the behavior can become a second-order XSS gadget because a security-relevant attribute is removed from normal elements but remains on allowed custom elements.

Possible fixes or mitigations might include

• ensuring that allowed custom elements also consistently pass through afterSanitizeElements
• documenting clearly that elements preserved via CUSTOM_ELEMENT_HANDLING may not participate in the same post-element hook flow as normal allowlisted elements.

🧱 New component testing model

Component testing moves to a stories and galleries model.
A story wraps your component in one specific scenario — hard-coded props, mock data, providers — and a gallery page that you serve renders stories on demand.
The new fixtures.mount() fixture navigates to the gallery, mounts a story by id, and returns a Locator scoped to the story's root element:

test('click should expand', async ({ mount }) => {
  const component = await mount('components/Expandable/Stateful');
  await component.getByRole('button').click();
  await expect(component.getByTestId('expanded')).toHaveValue('true');
});

Pass a story type as a template argument to type-check its props, and use update(props) / unmount() on the returned locator to re-render or tear down within a test.

🛑 Cancel operations with AbortSignal

Most operations and web-first assertions now accept a signal option that takes an AbortSignal, letting you cancel long-running actions, navigations, waits, and assertions:

const controller = new AbortController();
setTimeout(() => controller.abort(), 1000);

await page.getByRole('button', { name: 'Submit' }).click({ signal: controller.signal });
await expect(page.getByText('Done')).toBeVisible({ signal: controller.signal });

Providing a signal does not disable the default timeout; pass timeout: 0 to disable it.

🖼️ WebP screenshots

expect(page).toHaveScreenshot() and expect(locator).toHaveScreenshot() can now store snapshots in the WebP format — just give the snapshot a .webp name:

// Visual comparisons store the golden snapshot as lossless WebP.
await expect(page).toHaveScreenshot('homepage.webp');

// Standalone screenshots can trade quality for size with lossy WebP.
await page.screenshot({ path: 'homepage.webp', quality: 50 });

page.screenshot() and [locator.screenshot() (https://playwright.dev/docs/api/class-locator#locator-screenshot) also accept webp as a type, where quality 100 (the default) is lossless and lower values use lossy compression.

🧩 Custom test filtering with Reporter.preprocess()

New reporter.preprocess() hook runs after the configuration is resolved and before reporter.onBegin(), letting a reporter mark individual tests as skipped, excluded, fixed, or failing through a TestRun object:

class MyReporter {
  async preprocess({ config, suite, testRun }) {
    for (const test of suite.allTests()) {
      if (shouldSkip(test))
        testRun.skip(test);
    }
  }
}

🔁 Isolated retries

New testConfig.retryStrategy controls when failed tests are retried.
The default 'immediate' retries as soon as a worker is free; 'isolated' runs all retries at the end, one by one in a single worker, to minimize interference with the rest of the suite:

// playwright.config.ts
export default defineConfig({
  retries: 2,
  retryStrategy: 'isolated',
});

New APIs

Browser and Context

• New option credentials includes the context's virtual WebAuthn Credentials (passkeys) in the storage state, so they can be persisted and re-seeded into later contexts.

Actions

• New scroll option ("auto" | "none") on actions to opt out of Playwright's automatic scroll-into-view.

Network

• New apiResponse.timing() returns resource timing information for an API response.

Evaluation

• New locator.waitForFunction() waits until a function — called with the matching element — returns a truthy value.
• page.evaluate() and related methods now accept functions as evaluate arguments.
• page.addInitScript() / browserContext.addInitScript() now accept functions as init-script arguments.

Command line & MCP

• Playwright now bundles the Playwright MCP server and playwright-cli, runnable via npx playwright mcp and npx playwright cli.

Reporters

• The HTML report's Merge files grouping — previously only a UI toggle — can now be enabled from the config with the new mergeFiles reporter option:

// playwright.config.ts
export default defineConfig({
  reporter: [['html', { mergeFiles: true }]],
});

Announcements

• ⚠️ Debian 11 is not supported anymore.

Browser Versions

• Chromium 151.0.7922.34
• Mozilla Firefox 153.0
• WebKit 26.5

This version was also tested against the following stable channels:

TypeScript: Preserve quotes for methods named new (#​19621 by @​kovsu)

// Input
interface Container {
  "new"(id: string): number;
}

// Prettier 3.9.5
interface Container {
  new(id: string): number;
}

// Prettier 3.9.6
interface Container {

TypeScript: Support import defer (#​19624, #​19675 by @​fisker)

// Input
import defer * as foo from "foo";

// Prettier 3.9.5
import * as foo from "foo";

// Prettier 3.9.6
import defer * as foo from "foo";

JavaScript: Added a new official plugin @prettier/plugin-yuku (#​19628, #​19629 by @​fisker)

@prettier/plugin-yuku is powered by Yuku (A high-performance JavaScript/TypeScript compiler toolchain written in Zig).

This plugin includes two new parsers: yuku (JavaScript syntax) and yuku-ts (TypeScript syntax).

To use this plugin:

1. Install the plugin:

   yarn add --dev prettier @​prettier/plugin-yuku

2. Add it to your .prettierrc:

   plugins:
     - "@​prettier/plugin-yuku"

Due to package size limitations, this plugin is not bundled with the main prettier package and must be installed separately.

For more information, check the package homepage.

Big thanks to @​arshad-yaseen for his excellent work.

• Avoid emitting rgb() or rgba() functions with non-percent decimal
  channels. Older browsers only support integer values or (potentially decimal)
  percentages for these functions, so in order to preserve
  backwards-compatibility while retaining full precision for modern browsers,
  legacy colors that contain at least one non-integer channel will now use
  percentages for their channels (for example, rgb(0%, 100%, 50%) rather than
  rgb(0, 255, 127.5)).

• Fix a bug where the values of plain-CSS if() expressions were emitted using
  their meta.inspect() format rather than their CSS serialization format.

Minor Changes

• Default experiments.typescript to "auto", enabling built-in TypeScript support on Node.js >= 22.6 when no TypeScript loader is registered. (by @​alexander-akait in #​21477)

• Default experiments.css, experiments.html and experiments.asyncWebAssembly to "auto", enabling built-in support unless a loader is registered for those files; modules with inline or hook-injected loaders (e.g. html-webpack-plugin templates) keep being parsed as JavaScript. (by @​alexander-akait in #​21477)

• Add output.resourceHints to emit resource hints (preload/prefetch/modulepreload/preconnect), on by default for ESM output, plus module.parser.<type>.urlHints, css.fontPreload and javascript.dynamicImportCssPreload. (by @​alexander-akait in #​21477)

• Add built-in build progress via infrastructureLogging.progress, plus estimatedTime, phaseTimings, progress bar width and progressBar: "auto" on ProgressPlugin. (by @​alexander-akait in #​21477)

• Concatenate CommonJS modules with statically analyzable exports; opt out via optimization.concatenateModules: { commonjs: false }. (by @​alexander-akait in #​21477)

• Wrap "weird" CommonJS modules into module concatenation instead of bailing out. (by @​alexander-akait in #​21477)

• Add output.html.inline (true | "script" | "style") and the webpackInline magic comment to inline chunk content into HTML. (by @​alexander-akait in #​21477)

• Add output.html.inject to control where chunk tags are injected. (by @​alexander-akait in #​21477)

• Add output.html.title, output.html.meta and output.html.base options for head generation. (by @​alexander-akait in #​21477)

• Support per-icon link attributes (sizes, media, color, type, crossorigin) and arrays in output.html.favicon. (by @​alexander-akait in #​21487)

• Add output.html.manifest to generate and link a web app manifest with hashed icons. (by
