NewCVE-2026-71314 (opens in a new tab)How to fix?
Upgrade nuxt to version 3.21.10, 4.5.1 or higher.
Overview
Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input via the v-for in server-side rendering of islands or server components. An attacker can cause the server to allocate excessive memory and crash by sending a request with a large integer value for a prop used in v-for, leading to unbounded expansion during rendering. This can be exploited remotely without authentication by crafting requests that trigger excessive iteration counts in the rendering logic.
Workaround
This vulnerability can be mitigated by clamping the prop value used in v-for within server components (e.g., using v-for="n in Math.min(count, 1000)"), or by avoiding the use of v-for directly over an unclamped prop.
