This vulnerability allows for a potential Denial of Service (DoS) condition due to excessive CPU consumption, impacting Vercel's Next.js framework. The affected versions are from the 10.x to 14.x branches, prior to version 14.2.7. Organizations using these versions should be aware of the risks associated with this vulnerability.
The CVSS score of 5.9 indicates a medium severity level. While the risk is not classified as critical, it is significant enough to warrant attention. The exploitation status is currently classified as not exploitable, which means there are no known active exploits in the wild. However, organizations should still prioritize patching to mitigate any potential risks.
Organizations should prioritize patching immediately. The affected versions are 10.x, 11.x, 12.x, 13.x, and 14.x prior to version 14.2.7. The vulnerability can be mitigated by upgrading to the patched version or by configuring the `next.config.js` file with appropriate settings.
The issue was fully patched in Next.js version 14.2.7. Users should ensure their configurations are updated to prevent any potential issues arising from this vulnerability.
Vulnerability Details
The vulnerability in question affects the image optimization feature of Next.js, and it was identified in multiple versions leading up to 14.2.7. This vulnerability can lead to a Denial of Service condition, characterized by excessive CPU usage, which may impact the performance of applications utilizing this framework.
The official description categorizes this vulnerability under CWE-674, which pertains to improper control of a resource through its lifetime. The vulnerability was published on October 14, 2024, and has been given a CVSS score of 5.9, indicating a medium level of severity.
Technical Analysis
The root cause of this vulnerability lies in how Next.js handles image optimization. When certain configurations are not properly set, it allows for conditions that lead to excessive CPU usage, effectively causing a Denial of Service. The attack vector is classified as NETWORK, meaning it can be exploited remotely.
The attack complexity is rated as high, indicating that an attacker would need to have a good understanding of Next.js configurations and how to exploit this vulnerability effectively. There are no privileges required, and no user interaction is needed to exploit this vulnerability.
In terms of impact, the availability is high, as it can lead to significant disruptions in service. However, there are no confidentiality or integrity impacts associated with this vulnerability.
Risk & Impact Analysis
Risk to organizations includes potential service interruptions due to CPU exhaustion. The DoS condition could impact user access and overall application performance. Given that this vulnerability affects multiple branches of Next.js, the blast radius is considerable, especially for organizations heavily reliant on Vercel's hosting.
Organizations should address this vulnerability in their priority patch cycle, as the potential for service disruption can significantly affect user experience and operational capabilities.

|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions prior to vendor patch in Next.js are affected, specifically 10.x, 11.x, 12.x, 13.x, and 14.x branches before version 14.2.7. Users should ensure they upgrade to this version or later to avoid vulnerabilities.
Mitigation & Remediation
To remediate this vulnerability, organizations should upgrade to Next.js version 14.2.7 or later. Alternatively, as a temporary workaround, ensure that the `next.config.js` file has either `images.unoptimized`, `images.loader`, or `images.loaderFile` assigned. This will help mitigate the risk of excessive CPU consumption.
