Next.js: Remote Code Execution in next/og ImageResponse

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

## 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`.
