# GHSA-vcvr-r3jv-pc5j: Next.js: Remote Code Execution in next/og ImageResponse

> Remote code execution in Next.js ImageResponse allows attackers to execute arbitrary code via crafted SVG inputs in Node.js environments.

- **Severity:** Not scored
- **Exploited in the wild:** Not known
- **Login needed:** Not needed
- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 30 Sep 2026

## What is GHSA-vcvr-r3jv-pc5j?

GHSA-vcvr-r3jv-pc5j is a code injection vulnerability in next, published on 30 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

## Impact

The Node.js `ImageResponse` implementation from `next/og` is affected by an upstream vulnerability. This can lead to remote code execution.

Affected applications pass attacker-controlled values into SVG content, attributes, or styles during image generation:

```tsx
import { ImageResponse } from 'next/og'

export async function GET(request: Request) {
  const value = new URL(request.url).searchParams.get('value') ?? ''

  return new ImageResponse(
    <svg width="1200" height="630">
      <title>{value}</title>
    </svg>
  )
}
```

Applications using the Edge `ImageResponse` implementation, or applications that do not pass attacker-controlled values into SVG content, attributes, or styles, are not affected.

## Workaround

If upgrading is not immediately possible, do not pass attacker-controlled values into SVG content, attributes, or styles rendered by the Node.js `ImageResponse` implementation from `next/og`.

## Which versions are affected by GHSA-vcvr-r3jv-pc5j?

2 open source packages ship an affected version, including next.


| Package | Ecosystem | Affected | Fixed in |
| --- | --- | --- | --- |
| `next` | npm | From 16.2.0 | 16.3.6 |
| `next` | npm | From 16.2.0 | 16.3.6 |

## How do I fix GHSA-vcvr-r3jv-pc5j?

Upgrade next to 16.3.6 or later.

## Is GHSA-vcvr-r3jv-pc5j being exploited?

What it is: GHSA-vcvr-r3jv-pc5j is a code injection vulnerability in next, published on 30 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of GHSA-vcvr-r3jv-pc5j in the wild and no public exploit code.

Affected packages and fixed versions:
- next (npm): affected from 16.2.0; fixed in 16.3.6
- next (npm): affected from 16.2.0; fixed in 16.3.6

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
