Summary
Denial of Service Vulnerability in next.js
Details
Impact
Vulnerable code could allow a bad actor to trigger a denial of service attack for anyone running a Next.js app at version >= 12.0.0, and using i18n functionality.
- Affected: All of the following must be true to be affected by this CVE
- Next.js versions above v12.0.0
- Using next start or a custom server
- Using the built-in i18n support
- Not affected:
- Deployments on Vercel (vercel.com) are not affected along with similar environments where invalid requests are filtered before reaching Next.js.
Patches
A patch has been released, next@12.0.9, that mitigates this issue. We recommend all affected users upgrade as soon as possible.
Workarounds
We recommend upgrading whether you can reproduce or not although you can ensure /${locale}/_next/ is blocked from reaching the Next.js instance until you upgrade.
