Описание
Next.js is a React framework for building full-stack web applications. Starting in version 10.0.0 and prior to version 16.1.7, the default Next.js image optimization disk cache (/_next/image) did not have a configurable upper bound, allowing unbounded cache growth. An attacker could generate many unique image-optimization variants and exhaust disk space, causing denial of service. This is fixed in version 16.1.7 by adding an LRU-backed disk cache with images.maximumDiskCacheSize, including eviction of least-recently-used entries when the limit is exceeded. Setting maximumDiskCacheSize: 0 disables disk caching. If upgrading is not immediately possible, periodically clean .next/cache/images and/or reduce variant cardinality (e.g., tighten values for images.localPatterns, images.remotePatterns, and images.qualities).
An unbounded disk usage flaw has been discovered in Next.js. The default Next.js image optimization disk cache (/_next/image) did not have a configurable upper bound, allowing unbounded cache growth. An attacker could generate many unique image-optimization variants and exhaust disk space, causing denial of service.
Отчет
This vulnerability is rated as Moderate because, while an unauthenticated remote user can trigger unbounded cache allocation to exhaust filesystem storage and degrade service availability, it does not allow code execution or compromise data integrity and confidentiality. Within Red Hat environments utilizing Next.js web applications, the flaw is restricted to deployments actively serving image optimization endpoints directly from persistent local storage. Deployments that offload image handling or operate behind caching proxies with strict request and file quotas will experience limited disruption.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
