next@12.3.2-canary.34 vulnerabilities

next is a react framework.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of an upper bound on the disk cache used by the image optimization. An attacker can exhaust disk storage by generating a large number of unique image optimization variants, leading to service disruption.

Upgrade next to version 16.1.7, 16.2.0-canary.54 or higher.

next is a react framework.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the fetchExternalImage() function, which is used for image optimization and loads external images into memory without a maximum size limit. An attacker can exhaust system memory and disrupt service availability by requesting optimization of very large images from external domains.

Note:

This is only exploitable if remotePatterns is configured to allow image optimization from external domains and the attacker can serve or control a large image on an allowed domain.

Upgrade next to version 15.5.10, 16.1.1-canary.15, 16.1.5 or higher.

next is a react framework.

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the resolve-routes. An attacker can access internal resources and potentially exfiltrate sensitive information by crafting requests containing user-controlled headers (e.g., Location) that are forwarded or interpreted without validation.

Note: This is only exploitable if custom middleware logic is implemented in a self-hosted deployment. The project maintainers recommend using the documented NextResponse.next({request}) to explicitly pass the request object.

Upgrade next to version 14.2.32, 15.4.2-canary.43, 15.4.7 or higher.

next is a react framework.

Affected versions of this package are vulnerable to Use of Cache Containing Sensitive Information in the image optimization process, when responses from API routes vary based on request headers such as Cookie or Authorization. An attacker can gain unauthorized access to sensitive image data by exploiting cache key confusion, causing responses intended for authenticated users to be served to unauthorized users.

Note: Exploitation requires a prior authorized request to populate the cache.

Upgrade next to version 14.2.31, 15.4.2-canary.19, 15.4.5 or higher.

next is a react framework.

Affected versions of this package are vulnerable to Missing Source Correlation of Multiple Independent Data in image-optimizer. An attacker can cause arbitrary files to be downloaded with attacker-controlled content and filenames by supplying malicious external image sources.

Note: This is only exploitable if the application is configured to allow external image sources via the images.domains or images.remotePatterns configuration.

Upgrade next to version 14.2.31, 15.4.2-canary.19, 15.4.5 or higher.

next is a react framework.

Affected versions of this package are vulnerable to Race Condition in the Pages Router. An attacker can cause the server to serve incorrect pageProps data instead of the expected HTML content by exploiting a race condition between two requests, one containing the ?__nextDataRequest=1 query parameter and another with the x-now-route-matches header.

Notes:

1. This is only exploitable if the CDN provider caches a 200 OK response even in the absence of explicit cache-control headers, enabling a poisoned response to persist and be served to subsequent users;

2. No backend access or privileged escalation is possible through this vulnerability;

3. Applications hosted on Vercel's platform are not affected by this issue, as the platform does not cache responses based solely on 200 OK status without explicit cache-control headers.

4. This is a bypass of the fix for CVE-2024-46982

Upgrade next to version 14.2.24, 15.1.6 or higher.

next is a react framework.

Affected versions of this package are vulnerable to Improper Authorization due to the improper handling of the x-middleware-subrequest header. An attacker can bypass authorization checks by sending crafted requests containing this specific header.

Upgrade next to version 12.3.5, 13.5.9, 14.2.25, 15.2.3, 15.3.0-canary.12 or higher.

next is a react framework.

Affected versions of this package are vulnerable to Missing Authorization when using pathname-based checks in middleware for authorization decisions. If i18n configuration is not configured, an attacker can get unintended access to pages one level under the application's root directory.

e.g. https://example.com/foo is accessible. https://example.com/ and https://example.com/foo/bar are not.

Note:

Only self-hosted applications are vulnerable. The vulnerability has been fixed by Vercel on the server side.

Upgrade next to version 13.5.8, 14.2.15, 15.0.0-canary.177 or higher.

next is a react framework.

Affected versions of this package are vulnerable to Uncontrolled Recursion through the image optimization feature. An attacker can cause excessive CPU consumption by exploiting this vulnerability.

Upgrade next to version 14.2.7, 15.0.0-canary.109 or higher.
