Description

Impact

The image optimization feature of Next.js contained a vulnerability which allowed for a potential Denial of Service (DoS) condition which could lead to excessive CPU consumption.

Not affected:

  • The next.config.js file is configured with images.unoptimized set to true or images.loader set to a non-default value.
  • The Next.js application is hosted on Vercel.

Patches

This issue was fully patched in Next.js 14.2.7. We recommend that users upgrade to at least this version.

Workarounds

Ensure that the next.config.js file has either images.unoptimized, images.loader or images.loaderFile assigned.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
