SCA: security update for quasar (GHSA-68jq-fhch-4xq4)

high Tenable Cloud Security Plugin ID 473714

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 2.23.3,
 Platform.parseSSR() passed an unbounded User-Agent request header to getMatch() in
 ui/src/plugins/platform/Platform.js, whose browser-detection expressions combined greedy captures with
 repeated unbounded scans. Platform belongs to autoInstalledPlugins, so this parsing occurs before routing
 for every SSR request. A crafted unauthenticated request containing repeated version tokens without a
 terminating Safari token causes super-linear backtracking and blocks the Node.js event loop, delaying
 every other SSR request. SPA, PWA, Electron, Cordova, Capacitor, browser-extension, and static-site-
 generation targets are not affected because they do not parse an attacker-controlled request header
 through this path. This issue is fixed in version 2.23.3. (CVE-2026-106104)

Solution

Update the quasar library and its related packages to version 2.23.3 or later.
