CVE-2026-71316Network attack vectorHinoki check available

Unauthenticated SSR data disclosure via path-keyed payload cache

Published Aug 5, 2026 · Updated Aug 5, 2026

Information disclosure in Nuxt 4.4.0 through 4.5.0 allows remote attackers to read another user's SSR payload via an HTTP request. The runtime renderer stores cache:nuxt:payload entries under path-only keys and returns them before route middleware or page guards run. Exploitation requires a cache, swr, or isr route with payload extraction and user-specific SSR data that another user has already warmed.
