- Qwik: Crashing any Qwik Server via Resource thenable
- Details
-
Summary
A Qwik server in the default configuration can be crashed with one unauthenticated HTTP request. During qwik-json body parsing,
ResourceSerializer.$fill$doesPromise.resolve(resource._resolved). If_resolvedis a plain object whose.thenis a QRL for an unregistered symbol, the async QRL rejects, the rejection is orphaned, and Node terminates the process via its default unhandled-rejection policy.Impact
One unauthenticated request crashes the server. Looping keeps every replica dead as long as the attacker sends requests.
