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.","state":0,"publishedAt":"2026-10-06T18:16:51.687+00:00","modifiedAt":"2026-10-09T02:16:57.307+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.7,"severity":"HIGH"}],"references":["https://github.com/quasarframework/quasar/commit/7a954ddafa756afe95c8f633f48ed68a07209d3d","https://github.com/quasarframework/quasar/releases/tag/quasar-v2.23.3","https://github.com/quasarframework/quasar/security/advisories/GHSA-68jq-fhch-4xq4"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-106104","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-1333"],"productCriteria":[],"sourceDates":{"published":"2026-10-06T18:16:51.687","lastModified":"2026-10-09T02:16:57.307"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
