SCA: security update for @builder.io/qwik-city (GHSA-xqg6-98cw-gxhq)

critical Tenable Cloud Security Plugin ID 437481

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 version 1.19.0, a prototype pollution
 vulnerability exists in the formToObj() function within @builder.io/qwik-city middleware. The function
 processes form field names with dot notation (e.g., user.name) to create nested objects, but fails to
 sanitize dangerous property names like __proto__, constructor, and prototype. This allows unauthenticated
 attackers to pollute Object.prototype by sending crafted HTTP POST requests, potentially leading to
 privilege escalation, authentication bypass, or denial of service. This issue has been patched in version
 1.19.0. (CVE-2026-25150)
