CVE-2026-27980— Next.js: Unbounded next/image disk cache growth can exhaust storage

Next.js: Unbounded next/image disk cache growth can exhaust storage

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`).

未加控制的资源消耗(资源穷尽)

Next.js 资源管理错误漏洞

Next.js是Vercel开源的一个 React 框架。 Next.js 10.0.0至16.1.7之前版本存在资源管理错误漏洞，该漏洞源于默认图像优化磁盘缓存无配置上限，可能导致耗尽磁盘空间，引发拒绝服务攻击。
