How severe is GHSA-rcvg-rgf7-pppv?

GHSA-rcvg-rgf7-pppv has a CVSS score of 8.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-rcvg-rgf7-pppv?

GHSA-rcvg-rgf7-pppv affects the following packages: @nuxt/devtools (npm). Ecosystems affected: npm.

How do I fix GHSA-rcvg-rgf7-pppv?

Update @nuxt/devtools to 1.3.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rcvg-rgf7-pppv is resolved across your whole dependency graph.

How do I detect GHSA-rcvg-rgf7-pppv in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @nuxt/devtools. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-rcvg-rgf7-pppv if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-rcvg-rgf7-pppv?

O3 pinpoints whether GHSA-rcvg-rgf7-pppv is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-rcvg-rgf7-pppv actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-rcvg-rgf7-pppv, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-rcvg-rgf7-pppv?

GHSA-rcvg-rgf7-pppv has an EPSS (Exploit Prediction Scoring System) score of 1.1%, placing it in the 63th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-rcvg-rgf7-pppv?

GHSA-rcvg-rgf7-pppv is classified as Path Traversal (CWE-22), CWE-24 (CWE-24). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-rcvg-rgf7-pppv published, and has it been updated?

GHSA-rcvg-rgf7-pppv was published on August 5, 2024 and was last updated on August 6, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Summary

Nuxt Devtools is missing authentication on the getTextAssetContent RPC function which is vulnerable to path traversal. Combined with a lack of Origin checks on the WebSocket handler, an attacker is able to interact with a locally running devtools instance and exfiltrate data abusing this vulnerability.

In certain configurations an attacker could leak the devtools authentication token and then abuse other RPC functions to achieve RCE.

Details

The getTextAssetContent function does not check for path traversals (source), this could allow an attacker to read arbitrary files over the RPC WebSocket.

The WebSocket server does not check the origin of the request (source) leading to CSWSH. This may be intentional to allow certain configurations to work correctly.

Nuxt Devtools authentication tokens are placed within the home directory of the current user (source).

In the scenario that:

The user has a Nuxt3 Project running
Devtools is enabled and running
The project is placed within the users home directory.
The user visits a malicious webpage
User has authenticated with devtools at least once

The malicious webpage can connect to the Devtools WebSocket, perform a directory traversal brute force to find the authentication token, then use the authenticated writeStaticAssets function to create a new Component, Nitro Handler or app.vue file which will run automatically as the file is changed.

PoC

POC will exploit the Devtools server on localhost:3000 (you may need to manually restart the server as the restart hook does not always work).

POC: https://devtools-exploit.pages.dev

Create a new project with nuxt.new.
Place the project inside your home directory.
Run pnpm run dev.
Open the POC page.

The POC will:

Identify devtools version.
Leak your devtools token.
Create a new server handler with an insecure eval.

Impact

All new Nuxt projects by default (devtools is enabled) are vulnerable to arbitrary file read.
Certain Nuxt configurations are vulnerable to Remote Code Execution
