{"id":"CVE-2026-72744","aliases":["GHSA-7c4v-fwgw-9rf7"],"url":"https://o3.security/vulnerability/CVE-2026-72744","summary":"Nuxt before 4.5.1 Information Disclosure via Chrome DevTools","details":"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.","published":"2026-08-11T12:16:58.926Z","modified":"2026-08-13T03:52:06.775261862Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"nuxt","fixedVersion":"4.5.1"},{"ecosystem":"npm","name":"nuxt","fixedVersion":"3.21.10"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72744.json"},{"type":"ADVISORY","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":"ADVISORY","url":"https://www.vulncheck.com/advisories/nuxt-before-information-disclosure-via-chrome-devtools"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T03:52:06.775261862Z"}}
