CVE-2026-71314 (nuxt) — CWE-400 / CVSS v3 7.5
Attack vector: remote (network-reachable) / unauthenticated / no user interaction
Attack surface: `ssrRenderList` / `vforToArray`
Patched: `3.21.10` — apply immediately
Workaround: Avoid `v-for` directly over an unclamped prop in server components, or clamp the count in the component (`v-for="n in Math.min(count, 1000)"`).
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
