{"id":"GHSA-4jjw-pwvw-q6w3","summary":"Duplicate Advisory: Nuxt dev server discloses project root and workspace UUID via the Chrome DevTools workspace endpoint","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-7c4v-fwgw-9rf7. This link is maintained to preserve external references.\n\n## Original Description\nNuxt versions \u003e= 4.4.7 and \u003c 4.5.1, and \u003e= 3.21.7 and \u003c 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 Fixed in 4.5.1 and 3.21.10.","modified":"2026-08-13T14:30:09.419637647Z","published":"2026-08-11T15:32:37Z","withdrawn":"2026-08-13T14:18:02Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-08-13T14:18:02Z","nvd_published_at":"2026-08-11T13:19:05Z","cwe_ids":["CWE-200"]},"references":[{"type":"WEB","url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-7c4v-fwgw-9rf7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72744"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/nuxt-before-information-disclosure-via-chrome-devtools"}],"affected":[{"package":{"name":"nuxt","ecosystem":"npm","purl":"pkg:npm/nuxt"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.4.7"}]}],"database_specific":{"last_known_affected_version_range":"\u003c 4.5.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-4jjw-pwvw-q6w3/GHSA-4jjw-pwvw-q6w3.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"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/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"}]}
