A request with no `Sec-Fetch-Site`, `Origin`, and `Referer` headers (normal for a non-browser client such as `curl`) is treated as local, and the `Host` allow-list is compared against the attacker-supplied `Host` header. As a result, any unauthenticated host that can reach the dev server on the LAN can retrieve the project's absolute filesystem path and workspace UUID, for example with `curl -H 'Host: localhost' http://<dev-host-lan-ip>:3000/.well-known/appspecific/com.chrome.devtools.json`.\n\nThis is information disclosure only: there is no file read, file write, or code execution reachable from the endpoint. It requires the dev server to be reachable beyond loopback and `experimental.chromeDevtoolsProjectSettings` to be enabled (it defaults to `true`). Production builds are unaffected, because the endpoint is registered only as a development handler.\n\n### Patches\n\nFixed in `nuxt@4.5.1` and `nuxt@3.21.10`. The endpoint now additionally requires the connected TCP peer to be a loopback address, verified from the socket rather than from request headers, so a non-loopback LAN client is rejected regardless of the `Host`, `Origin`, `Referer`, or `Sec-Fetch-*` headers it sends. The shared header-based check is left unchanged, so the CSRF / same-origin behaviour that other dev handlers rely on is preserved. After this fix, Chrome DevTools workspace auto-mapping only works when the browser reaches the dev server over loopback (`localhost` / `127.0.0.1` / `::1`), which matches the feature's intent (the browser and dev server sharing a filesystem).\n\n### Workarounds\n\n- Do not bind the dev server to a non-loopback interface on an untrusted network, or restrict access to the dev port with a firewall.\n- Disable the feature by setting `experimental.chromeDevtoolsProjectSettings: false` in `nuxt.config`.","state":0,"publishedAt":"2026-08-07T16:45:21+00:00","modifiedAt":"2026-08-13T14:30:09.2194976+00:00","affected":[{"ecosystem":"npm","name":"nuxt","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"4.4.7"},{"kind":"fixed","version":"4.5.1"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"nuxt","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"3.21.7"},{"kind":"fixed","version":"3.21.10"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/nuxt/nuxt/security/advisories/GHSA-7c4v-fwgw-9rf7","https://nvd.nist.gov/vuln/detail/CVE-2026-72744","https://github.com/nuxt/nuxt/commit/00f71bb6517abff67257c8ea1fcdc777b938b68d","https://github.com/nuxt/nuxt/commit/e30c611ea03240f341fe784ab1711aa6424da2fa","https://github.com/nuxt/nuxt","https://github.com/nuxt/nuxt/releases/tag/v3.21.10","https://github.com/nuxt/nuxt/releases/tag/v4.5.1","https://www.vulncheck.com/advisories/nuxt-before-information-disclosure-via-chrome-devtools"],"sourceUrl":"https://github.com/advisories/GHSA-7c4v-fwgw-9rf7","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-7c4v-fwgw-9rf7","identifiers":["GHSA-7c4v-fwgw-9rf7","CVE-2026-72744"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
