{"id":"CVE-2026-72744","summary":"Nuxt before 4.5.1 Information Disclosure via Chrome DevTools","details":"Nuxt 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.","aliases":["GHSA-7c4v-fwgw-9rf7"],"modified":"2026-08-13T03:52:06.775261862Z","published":"2026-08-11T12:16:58.926Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72744.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-200"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nuxt/nuxt","events":[{"introduced":"b7d57903b947e788fadfcfdf88be7951943731bf"},{"fixed":"452dd50d92ccdf6f456b500e71d0f26baaeff796"},{"introduced":"fd806be61503f6ccad099c070a5d803777ba8a57"},{"fixed":"deafc94128005346ed8ef4dd5e64f940d80377d3"}],"database_specific":{"extracted_events":[{"introduced":"4.4.7"},{"fixed":"4.5.1"},{"introduced":"3.21.7"},{"fixed":"3.21.10"}],"source":"AFFECTED_FIELD"}}],"versions":["v3.21.9","v4.5.0","v3.21.8","v4.4.8","v4.4.7","v3.21.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72744.json"}}],"schema_version":"1.9.0","severity":[{"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"}]}
