{"cve":"CVE-2026-72744","nvd":{"published":"2026-08-11T13:19:05.210","modified":"2026-09-24T20:44:42.207","status":"Awaiting Analysis","description":"Nuxt versions >= 4.4.7 and < 4.5.1, and >= 3.21.7 and < 3.21.10, contain an information disclosure vulnerability in the development server's Chrome DevTools workspace endpoint (GET /.well-known/appspecific/com.chrome.devtools.json). The endpoint's local-request gate (isLocalDevRequest) is header-based and trusts the attacker-supplied Host header rather than the connected peer address. When the dev server is bound to a network-reachable interface (e.g. nuxt dev --host) and experimental.chromeDevtoolsProjectSettings is enabled (the default), an unauthenticated attacker on the LAN can send a request with a spoofed Host header and no browser-specific headers (Sec-Fetch-Site, Origin, Referer) to retrieve the project's absolute filesystem root path (rootDir) and a persistent per-project workspace UUID. Production builds are unaffected. Fixed in 4.5.1 and 3.21.10.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":6.2},"cwes":["CWE-200"],"references":["https://github.com/nuxt/nuxt/security/advisories/GHSA-7c4v-fwgw-9rf7","https://www.vulncheck.com/advisories/nuxt-before-information-disclosure-via-chrome-devtools"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-72744","score":0.00181,"percentile":0.0765,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7c4v-fwgw-9rf7","url":"https://osv.dev/vulnerability/GHSA-7c4v-fwgw-9rf7","summary":"Nuxt dev server discloses project root and workspace UUID via the Chrome DevTools workspace endpoint","modified":"2026-08-13T14:30:09.219497646Z","packages":[{"ecosystem":"npm","name":"nuxt","purl":"pkg:npm/nuxt","ranges":[">=4.4.7 <4.5.1"],"fixed":["4.5.1"]},{"ecosystem":"npm","name":"nuxt","purl":"pkg:npm/nuxt","ranges":[">=3.21.7 <3.21.10"],"fixed":["3.21.10"]}]}],"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).
