This upgrade is completely backwards compatible and recommended for all users on versions below 9.3.2. For future security related communications of our OSS projects, please join this mailing list.
Next.js has just been audited by one of the top security firms in the world.
They found that attackers could craft special requests to access files in the dist directory (.next).
This does not affect files outside of the dist directory (.next).
In general, the dist directory only holds build assets unless your application intentionally stores other assets under this directory.
We recommend upgrading to the latest version of Next.js to improve the overall security of your application.
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
Not affected: Deployments on ZEIT Now v2 (https://zeit.co) are not affected
Not affected: Deployments using the serverless target
Not affected: Deployments using next export
Affected: Users of Next.js below 9.3.2 that use next start
We recommend everyone to upgrade regardless of whether you can reproduce the issue or not.
How to Assess Impact
If you think sensitive code or data could have been exposed, you can filter logs of affected sites by ../ with a 200 response.
What is Being Done
As Next.js has grown in popularity, it has received the attention of security researchers and auditors. We are thankful to Luca Carettoni from Doyensec for their investigation and discovery of the original bug and subsequent responsible disclosure.
We've landed a patch that ensures only known filesystem paths of .next/static are made available under /_next/static.
Regression tests for this attack were added to the security integration test suite.
We have notified known Next.js users in advance of this publication.
A public CVE was issued.
