Inputs such as\n   `/..//evil.com`, `/.//evil.com`, `/%2e%2e//evil.com`, or\n   `/app/..//evil.com` slipped past that check because they start with\n   `/`, but WHATWG URL parsing then normalised them to the\n   protocol-relative pathname `//evil.com`. The normalised value was\n   written to the `Location` response header and into the\n   `\u003cmeta http-equiv=\"refresh\"\u003e` body of the SSR redirect page, so a\n   victim's browser would resolve the redirect cross-origin to the\n   attacker's host.\n\n2. **(CVE-2026-56698) Client-side script execution via `navigateTo({ open: ... })`.** The\n   client-side early-open handler called `window.open(toPath, ...)` without\n   applying the `isScriptProtocol` check that gates the normal `navigateTo`\n   path. A target of `javascript:...` (or another script-capable scheme)\n   passed to `navigateTo(url, { open: { ... } })` therefore executed in the\n   application's origin instead of being rejected.\n\n3. **(CVE-2026-56697) Open redirect in `reloadNuxtApp` via protocol-relative bypass.**\n   `reloadNuxtApp({ path })` rejects script-capable protocols by parsing\n   the path with `new URL(path, window.location.href)` and checking the\n   resolved `protocol` against `isScriptProtocol`. Protocol-relative paths\n   such as `//evil.com` resolve to the current page's protocol (`https:`),\n   which passes that check; the value is then assigned to\n   `window.location.href`, which the browser treats as a cross-origin\n   redirect. This is the same protocol-relative bypass family as (1), in\n   a different sink.\n\n### Impact\n\nFor (1), the practical risk is phishing or OAuth-code theft against any\nNuxt app that forwards user-controlled input (for example a `?next=`\nquery parameter on a login route) into `navigateTo` on the server. The\nframework documents that `navigateTo` blocks external hosts unless\n`external: true` is passed, so maintainers commonly rely on it as the\nsafe path for post-login redirects.\n\nFor (2), any app that passes a user-controlled URL into\n`navigateTo(url, { open: { ... } })` was vulnerable to reflected XSS in\nthe application's first-party origin.\n\nFor (3), any app that forwards user-controlled input into\n`reloadNuxtApp({ path })` could be redirected cross-origin for phishing\nor OAuth-code theft, even on releases that already shipped the\n`isScriptProtocol` guard added by [#35115](https://github.com/nuxt/nuxt/pull/35115).\n\n### Patches\n\nFixed in `nuxt@4.4.7` and backported to `nuxt@3.21.7`. The three sinks\nare addressed by:\n\n- Path-normalisation bypass in `navigateTo`:\n  - 4.x: commit [`2cce6fb0`](https://github.com/nuxt/nuxt/commit/2cce6fb02e621196d56df92e05594e07469b5a6d)\n  - 3.x: commit [`1f2dd5e7`](https://github.com/nuxt/nuxt/commit/1f2dd5e78c77576437138e97671965573c232835)\n- `navigateTo({ open })` script-protocol guard:\n  - 4.x: [#35206](https://github.com/nuxt/nuxt/pull/35206) (commit [`3394716d`](https://github.com/nuxt/nuxt/commit/3394716d4a913cba904b028df5338f2aead50032))\n  - 3.x: commit [`62fc32ed`](https://github.com/nuxt/nuxt/commit/62fc32eddf648b00a3890141e0235d2a222b024d)\n- Protocol-relative bypass in `reloadNuxtApp`:\n  - 4.x: commit [`e447a793`](https://github.com/nuxt/nuxt/commit/e447a793c47766834f7497f8412a76cd56fd8ee1)\n  - 3.x: commit [`6497d99d`](https://github.com/nuxt/nuxt/commit/6497d99dd106254abd089f6a263d7773869a343b)\n\n### Workarounds\n\n- For (1): validate redirect targets before passing them to `navigateTo`,\n  for example reject any input where\n  `new URL(target, 'http://localhost').pathname` starts with `//`, or\n  only accept a known allow-list of paths.\n- For (2): reject any user-controlled URL whose protocol is not in an\n  allow-list (typically just `http:` and `https:`) before passing it to\n  `navigateTo({ open: ... })`.\n- For (3): same shape as (1). Reject paths starting with `//` (or where\n  `new URL(path, window.location.href).host !== window.location.host`)\n  before passing to `reloadNuxtApp({ path })`.\n\n### References\n\n- CWE-601: URL Redirection to Untrusted Site ('Open Redirect')\n- CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')\n\n### Credits\n\nReported by Anthropic / Claude as `ANT-2026-S08HN6DH` through Anthropic's\ncoordinated vulnerability disclosure programme.\n\nThe `reloadNuxtApp` protocol-relative bypass (sink 3) was independently\nreported by [@alcls01111](https://github.com/alcls01111) via GitHub's\ncoordinated disclosure flow (`GHSA-w7fp-2cfv-4837`), closed as a\nduplicate of this advisory.","status":"published","published":"2026-06-16T13:47:52Z","modified":"2026-09-18T20:43:02Z","cvss":[{"version":"4.0","score":5.1,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:L/SA:N","level":"medium"},{"version":"3.1","score":6.1,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","level":"medium"}],"cwes":["CWE-79","CWE-601"],"updated_at":"2026-11-02T14:41:19.455935Z"},{"id":"GHSA-rq7w-g337-39qq","title":"Nuxt: Dev server discloses project absolute path and persistent workspace UUID via `/.well-known/appspecific/com.chrome.devtools.json`","description":"### Summary\n\nWhen running `nuxt dev`, Nuxt registers an unauthenticated route at `/.well-known/appspecific/com.chrome.devtools.json` that returns the absolute filesystem path of the project root and a per-project UUID persisted to `node_modules/.cache/nuxt/chrome-workspace.json`. The route is enabled by default via `experimental.chromeDevtoolsProjectSettings: true`.\n\nThe endpoint exists to let Chrome DevTools' Workspace integration map sources to the developer's local checkout. The handler is registered directly on `nitro.options.devHandlers` and does not pass through the CORS / origin wrapper that the rest of the dev pipeline uses, so it has no host / origin / `Sec-Fetch-Site` check of its own.\n\n### Impact\n\nDev-server only. Production builds do not register the route.\n\nTwo values are disclosed:\n\n- `workspace.root`: the absolute filesystem path of the project (commonly reveals the OS username and the on-disk project name).\n- `workspace.uuid`: a v4 UUID persisted to `node_modules/.cache/nuxt/chrome-workspace.json`, stable across dev-server restarts and re-clones.\n\n### Threat model\n\nThe response carries no `Access-Control-Allow-Origin` header. A cross-origin `fetch()` from an arbitrary malicious page is therefore blocked by the browser's same-origin policy and cannot read the body. The two realistic recovery paths are:\n\n1. **LAN-adjacent attacker** when the developer runs `nuxt dev --host` (or otherwise binds to a non-loopback interface). A plain `curl http://\u003cdev-lan-ip\u003e:3000/.well-known/appspecific/com.chrome.devtools.json` returns the JSON; no browser, no CORS.\n2. **DNS rebinding** against the default loopback dev server. A page the developer visits resolves to the attacker, then re-resolves to `127.0.0.1` after the TTL; the browser believes the request is same-origin and reads the response.\n\n### Affected versions\n\n`nuxt@4.0.0-alpha.1` (PR #32084) through `nuxt@4.4.6`. `3.x` is not affected.\n\n### Reproduction\n\n```bash\nnpx nuxt dev\ncurl -s http://localhost:3000/.well-known/appspecific/com.chrome.devtools.json\n# {\"workspace\":{\"uuid\":\"...\",\"root\":\"/Users/\u003cname\u003e/...\"}}\n```\n\n### Workaround\n\nSet `experimental: { chromeDevtoolsProjectSettings: false }` in `nuxt.config.ts`.

Inputs such as\n   `/..//evil.com`, `/.//evil.com`, `/%2e%2e//evil.com`, or\n   `/app/..//evil.com` slipped past that check because they start with\n   `/`, but WHATWG URL parsing then normalised them to the\n   protocol-relative pathname `//evil.com`. The normalised value was\n   written to the `Location` response header and into the\n   `\u003cmeta http-equiv=\"refresh\"\u003e` body of the SSR redirect page, so a\n   victim's browser would resolve the redirect cross-origin to the\n   attacker's host.\n\n2. **(CVE-2026-56698) Client-side script execution via `navigateTo({ open: ... })`.** The\n   client-side early-open handler called `window.open(toPath, ...)` without\n   applying the `isScriptProtocol` check that gates the normal `navigateTo`\n   path. A target of `javascript:...` (or another script-capable scheme)\n   passed to `navigateTo(url, { open: { ... } })` therefore executed in the\n   application's origin instead of being rejected.\n\n3. **(CVE-2026-56697) Open redirect in `reloadNuxtApp` via protocol-relative bypass.**\n   `reloadNuxtApp({ path })` rejects script-capable protocols by parsing\n   the path with `new URL(path, window.location.href)` and checking the\n   resolved `protocol` against `isScriptProtocol`. Protocol-relative paths\n   such as `//evil.com` resolve to the current page's protocol (`https:`),\n   which passes that check; the value is then assigned to\n   `window.location.href`, which the browser treats as a cross-origin\n   redirect. This is the same protocol-relative bypass family as (1), in\n   a different sink.\n\n### Impact\n\nFor (1), the practical risk is phishing or OAuth-code theft against any\nNuxt app that forwards user-controlled input (for example a `?next=`\nquery parameter on a login route) into `navigateTo` on the server. The\nframework documents that `navigateTo` blocks external hosts unless\n`external: true` is passed, so maintainers commonly rely on it as the\nsafe path for post-login redirects.\n\nFor (2), any app that passes a user-controlled URL into\n`navigateTo(url, { open: { ... } })` was vulnerable to reflected XSS in\nthe application's first-party origin.\n\nFor (3), any app that forwards user-controlled input into\n`reloadNuxtApp({ path })` could be redirected cross-origin for phishing\nor OAuth-code theft, even on releases that already shipped the\n`isScriptProtocol` guard added by [#35115](https://github.com/nuxt/nuxt/pull/35115).\n\n### Patches\n\nFixed in `nuxt@4.4.7` and backported to `nuxt@3.21.7`. The three sinks\nare addressed by:\n\n- Path-normalisation bypass in `navigateTo`:\n  - 4.x: commit [`2cce6fb0`](https://github.com/nuxt/nuxt/commit/2cce6fb02e621196d56df92e05594e07469b5a6d)\n  - 3.x: commit [`1f2dd5e7`](https://github.com/nuxt/nuxt/commit/1f2dd5e78c77576437138e97671965573c232835)\n- `navigateTo({ open })` script-protocol guard:\n  - 4.x: [#35206](https://github.com/nuxt/nuxt/pull/35206) (commit [`3394716d`](https://github.com/nuxt/nuxt/commit/3394716d4a913cba904b028df5338f2aead50032))\n  - 3.x: commit [`62fc32ed`](https://github.com/nuxt/nuxt/commit/62fc32eddf648b00a3890141e0235d2a222b024d)\n- Protocol-relative bypass in `reloadNuxtApp`:\n  - 4.x: commit [`e447a793`](https://github.com/nuxt/nuxt/commit/e447a793c47766834f7497f8412a76cd56fd8ee1)\n  - 3.x: commit [`6497d99d`](https://github.com/nuxt/nuxt/commit/6497d99dd106254abd089f6a263d7773869a343b)\n\n### Workarounds\n\n- For (1): validate redirect targets before passing them to `navigateTo`,\n  for example reject any input where\n  `new URL(target, 'http://localhost').pathname` starts with `//`, or\n  only accept a known allow-list of paths.\n- For (2): reject any user-controlled URL whose protocol is not in an\n  allow-list (typically just `http:` and `https:`) before passing it to\n  `navigateTo({ open: ... })`.\n- For (3): same shape as (1). Reject paths starting with `//` (or where\n  `new URL(path, window.location.href).host !== window.location.host`)\n  before passing to `reloadNuxtApp({ path })`.\n\n### References\n\n- CWE-601: URL Redirection to Untrusted Site ('Open Redirect')\n- CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')\n\n### Credits\n\nReported by Anthropic / Claude as `ANT-2026-S08HN6DH` through Anthropic's\ncoordinated vulnerability disclosure programme.\n\nThe `reloadNuxtApp` protocol-relative bypass (sink 3) was independently\nreported by [@alcls01111](https://github.com/alcls01111) via GitHub's\ncoordinated disclosure flow (`GHSA-w7fp-2cfv-4837`), closed as a\nduplicate of this advisory.","status":"published","published":"2026-06-16T13:47:52Z","modified":"2026-10-03T05:30:03.679714841Z","cvss":[{"version":"3.1","score":6.1,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","level":"medium"},{"version":"4.0","score":5.1,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:L/SA:N","level":"medium"}],"cwes":["CWE-601","CWE-79"],"updated_at":"2026-11-02T15:46:44.927642Z"},{"id":"GHSA-rq7w-g337-39qq","title":"Nuxt: Dev server discloses project absolute path and persistent workspace UUID via `/.well-known/appspecific/com.chrome.devtools.json`","description":"### Summary\n\nWhen running `nuxt dev`, Nuxt registers an unauthenticated route at `/.well-known/appspecific/com.chrome.devtools.json` that returns the absolute filesystem path of the project root and a per-project UUID persisted to `node_modules/.cache/nuxt/chrome-workspace.json`. The route is enabled by default via `experimental.chromeDevtoolsProjectSettings: true`.\n\nThe endpoint exists to let Chrome DevTools' Workspace integration map sources to the developer's local checkout. The handler is registered directly on `nitro.options.devHandlers` and does not pass through the CORS / origin wrapper that the rest of the dev pipeline uses, so it has no host / origin / `Sec-Fetch-Site` check of its own.\n\n### Impact\n\nDev-server only. Production builds do not register the route.\n\nTwo values are disclosed:\n\n- `workspace.root`: the absolute filesystem path of the project (commonly reveals the OS username and the on-disk project name).\n- `workspace.uuid`: a v4 UUID persisted to `node_modules/.cache/nuxt/chrome-workspace.json`, stable across dev-server restarts and re-clones.\n\n### Threat model\n\nThe response carries no `Access-Control-Allow-Origin` header. A cross-origin `fetch()` from an arbitrary malicious page is therefore blocked by the browser's same-origin policy and cannot read the body. The two realistic recovery paths are:\n\n1. **LAN-adjacent attacker** when the developer runs `nuxt dev --host` (or otherwise binds to a non-loopback interface). A plain `curl http://\u003cdev-lan-ip\u003e:3000/.well-known/appspecific/com.chrome.devtools.json` returns the JSON; no browser, no CORS.\n2. **DNS rebinding** against the default loopback dev server. A page the developer visits resolves to the attacker, then re-resolves to `127.0.0.1` after the TTL; the browser believes the request is same-origin and reads the response.\n\n### Affected versions\n\n`nuxt@4.0.0-alpha.1` (PR #32084) through `nuxt@4.4.6`. `3.x` is not affected.\n\n### Reproduction\n\n```bash\nnpx nuxt dev\ncurl -s http://localhost:3000/.well-known/appspecific/com.chrome.devtools.json\n# {\"workspace\":{\"uuid\":\"...\",\"root\":\"/Users/\u003cname\u003e/...\"}}\n```\n\n### Workaround\n\nSet `experimental: { chromeDevtoolsProjectSettings: false }` in `nuxt.config.ts`. Chrome DevTools' Workspace auto-integration will stop working; the dev server is otherwise unaffected.\n\n### Patches\n\nFixed in `nuxt@4.4.7` by [#35201](https://github.com/nuxt/nuxt/pull/35201) (commit [`55c75b78`](https://github.com/nuxt/nuxt/commit/55c75b78c989b8bd210837b0e5faaebbf2b87b15)).
