chore(deps): bump next from 12.0.4 to 12.0.9

[dependabot]

Bumps next from 12.0.4 to 12.0.9.

Release notes

Sourced from next's releases.

v12.0.9

This upgrade is completely backward-compatible and recommended for all users on versions below 12.0.9

Vulnerable code could allow a bad actor to trigger a denial of service attack via the /${locale}/_next/ route for anyone running a Next.js app at version >= 12.0.0, and using built-in i18n routing functionality.

How to Upgrade

• We have released patch versions for both the stable and canary channels of Next.js.
• To upgrade run npm install next@latest --save

Impact

• Affected: All of the following must be true to be affected by this CVE
  • Next.js versions between v12.0.0 and v12.0.9
  • 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.

We recommend everyone to upgrade regardless of whether you can reproduce the issue or not.

How to Assess Impact

If your server has seen requests to any route under the prefix /${locale}/_next/ that have triggered a heap overflow error, this was caused by the patched issue.

What is Being Done

As Next.js has grown in popularity and usage by enterprises, it has received the attention of security researchers and auditors. We are thankful to our users for their investigation and responsible disclosure of the original bug.

We've landed a patch that ensures this is handled properly so the requested route no longer crashes and triggers a heap overflow.

Regression tests for this attack were added to the i18n integration test suite

• A public CVE was released.
• We encourage responsible disclosure of future reports. Please email us at [email protected]. We are actively monitoring this mailbox.
