SCA: security update for @builder.io/qwik, @qwik.dev/core (GHSA-x586-xvc8-g7q6)

high Tenable Cloud Security Plugin ID 474676

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Qwik is a performance-focused JavaScript framework. Prior to @builder.io/qwik 1.20.0 and @qwik.dev/core
2.0.0-beta.37, default server-side qwik-json deserialization causes ResourceSerializer.$fill$ to pass
resource._resolved to Promise.resolve without first rejecting attacker-controlled thenables. An
unauthenticated request can provide a plain object whose then property is a QRL for an unregistered
symbol, causing an orphaned asynchronous rejection that terminates Node.js under its default unhandled-
rejection policy. A single request can crash a server, and repeated requests can keep replicas
unavailable. This issue is fixed in @builder.io/qwik 1.20.0 and @qwik.dev/core 2.0.0-beta.37.
(CVE-2026-84994)

Solution

Update the @builder.io/qwik library and its related packages to version 1.20.0 or later.
