SCA: security update for @quasar/app-vite, @quasar/render-ssr-error (GHSA-r5mf-4r5x-q78f)

high Tenable Cloud Security Plugin ID 473692

Description

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

 - Quasar Framework is a framework for building high-performance Vue.js user interfaces. Prior to
 @quasar/render-ssr-error 2.2.4 and @quasar/app-vite 3.3.0, renderSSRError() in utils/render-ssr-
 error/src/index.js used diagnostic data from utils/render-ssr-error/src/env.js to serialize process.env,
 request headers, and cookies into the HTTP page returned by serve.devError(), while the development server
 listened on all interfaces by default. Any network-adjacent client that reaches an SSR or SSG render
 failure through this development-only error path can obtain shell environment secrets. The renderer
 escaped only one exact lowercase script closing-tag spelling, so case variants and valid closing-tag
 delimiter variants in reflected diagnostic data could terminate the script element and inject markup;
 executing the injected code in a developer browser additionally requires the payload to accompany that
 developer's request. This issue is fixed in @quasar/render-ssr-error 2.2.4 and @quasar/app-vite 3.3.0.
 (CVE-2026-106106)

Solution

Update the @quasar/render-ssr-error library and its related packages to version 2.2.4 or later.
