CVE ID :CVE-2026-94484
Published : Oct. 2, 2026, 4:16 p.m. | 56 minutes ago
Description :Next.js is a React framework for building full-stack web applications. From 15.0.0 until 15.5.27 and 16.3.8, applications with a root-level catch-all page and statically generated or Incremental Static Regeneration routes can use a shared response cache key that is insufficiently scoped to the source route. A single unauthenticated crafted request can poison that cache, causing cross-user content substitution or persistent denial of service until the poisoned entry is revalidated or replaced. This issue is fixed in versions 15.5.27 and 16.3.8.
