{"cve":"CVE-2026-106106","nvd":{"published":"2026-10-06T18:16:52.030","modified":"2026-10-06T20:03:40.690","status":"Awaiting Analysis","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:A/AC:H/AT:P/PR:N/UI:P/VC:H/VI:L/VA:N/SC:H/SI:H/SA:N","score":7.1},"cvss_v3":null,"cwes":["CWE-79","CWE-497"],"references":["https://github.com/quasarframework/quasar/commit/61c2bd8a607785fdade72cce20e8faf1de7eee15","https://github.com/quasarframework/quasar/releases/tag/@quasar/app-vite-v3.3.0","https://github.com/quasarframework/quasar/security/advisories/GHSA-r5mf-4r5x-q78f","https://github.com/quasarframework/quasar/security/advisories/GHSA-r5mf-4r5x-q78f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-106106","score":0.00276,"percentile":0.1983,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-r5mf-4r5x-q78f","url":"https://osv.dev/vulnerability/GHSA-r5mf-4r5x-q78f","summary":"Quasar Framework: SSR/SSG dev error page discloses the full shell environment and its </script> escape is bypassable","modified":"2026-10-07T16:30:05.799841829Z","packages":[{"ecosystem":"npm","name":"@quasar/render-ssr-error","purl":"pkg:npm/%40quasar/render-ssr-error","ranges":["<2.2.4"],"fixed":["2.2.4"]},{"ecosystem":"npm","name":"@quasar/app-vite","purl":"pkg:npm/%40quasar/app-vite","ranges":["<3.3.0"],"fixed":["3.3.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
