What it is
Files or folders that should be private can be fetched from outside.
How it is reached
An attacker can exploit it over the network, without an account, and nobody has to click anything. Success also depends on conditions the attacker does not fully control.
What an attacker gains
A successful attack can read the data it protects. In practice, this kind of flaw lets an attacker learn data or internals that help a follow-up attack.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade nuxt to 4.6.4 or later. Other affected products have their own fixed versions on this page.
- Until it is patched, keep it off the internet or behind a VPN, allowlist or authenticating proxy.
Description from NVD
Nuxt is an open-source web development framework for Vue.js. From 3.5.0 until 4.6.4, Nuxt can choose a parent directory as the default workspaceDir in either of two cases: a stray parent lockfile when the project is outside a Git repository and has no workspace file above it, or a parent pnpm or Deno settings file that does not declare packages or a workspace, including when the project is inside a Git repository. When the development server is reachable from an untrusted network, Vite permits /_nuxt/@fs/ requests beneath that widened directory, allowing unauthenticated clients to read files such as credentials and SSH keys. The issue affects the development server only; production builds and projects whose parent directories contain no qualifying files are unaffected. This issue is fixed in version 4.6.4.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Error responses, logs and debug endpoints. The flaw sits between internal data and whoever can read the response or log.
- APIs that over-share. The flaw sits between internal data and whoever can read the response or log.
Trust boundaries in play
- Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
- Between internal data and whoever can read the response or log. An attacker who crosses it can learn data or internals that help a follow-up attack.
Questions to answer about your own systems
- Where does nuxt run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
