Bumps happy-dom from 15.11.7 to 21.0.4.

Release notes

Sourced from happy-dom's releases.

v21.0.4

👷‍♂️ Patch fixes

• Fixed a code injection vulnerability in the ESM compiler - By @​capricorn86
• Fixed cross-origin isolation so opaque-origin data: iframes cannot access their parent or top window - By @​capricorn86

v21.0.3

👷‍♂️ Patch fixes

• Fixes security vulnerability where authorization header was forwarded when redirecting - By @​capricorn86

v21.0.2

👷‍♂️ Patch fixes

• Fixes SSRF security vulnerability by doing a target-origin bypass in the proxy server in @​happy-dom/server-renderer - By @​capricorn86

v21.0.1

👷‍♂️ Patch fixes

• Adds aliases --css and --iframe for enabling CSS and iframe loading to @​happy-dom/server-renderer - By @​capricorn86

v21.0.0

💣 Breaking Changes

• Disables CSS and IFrame loading by default to prevent server-side request forgery (SSRF) - By @​capricorn86
  • An attacker could embed <iframe> or <link rel="stylesheet"> elements in untrusted HTML to make Happy DOM send HTTP requests from the server to attacker-chosen URLs, including internal services. This could allow access to otherwise unreachable endpoints or trigger unintended actions, depending on the application and its network access.
  • The settings property disableCSSFileLoading has been deprecated
  • Added the new settings properties enableCSSFileLoading and enableIframePageLoading
  • If you don't believe that you are at risk, you can keep the same behavior as in <=v20.14.6 by sending in { enableCSSFileLoading: true, enableIframePageLoading: true } as broswer settings (e.g. new Window({ settings }));

v20.14.6

👷‍♂️ Patch fixes

• Fixes cookie scope forgery vulnerability - By @​capricorn86

v20.14.5

👷‍♂️ Patch fixes

• Preserve character references in comment data - By @​hampustagerud in task #2409

v20.14.4

👷‍♂️ Patch fixes

• End comments at the first comment end tag when it overlaps a comment start tag - By @​hampustagerud in task #2407

v20.14.3

👷‍♂️ Patch fixes

• Avoids cloning all properties in CSSPropertyManager.toString - By @​erictheswift in task #2363

v20.14.2

🔵 Needs a closer look

The v15-to-v21 DOM upgrade requires web/docs CI validation because test setup relies on Happy DOM internals and custom timer ownership that cannot be verified here.
