Next 16.2.6 carried ~20 advisories fixed in 16.4.x, including
unauthenticated RCE in the Image Optimization API (GHSA-2xp9-vwfh-vxw4,
GHSA-2464-fhr4-w9xw) and SSG/ISR cache poisoning (GHSA-mcj8-r9mp-w47p).
npm audit fix clears the remaining sharp/postcss/source-map-js/nanoid
findings; npm audit now reports 0 vulnerabilities.
Node 20 is EOL and receives no fix for Node2Shell (CVE-2026-111497,
bundled Brotli decoder OOB write). Pin .nvmrc and render.yaml to Node 24
LTS; Amplify SSR compute runs the major version used at build time.
- amplify.yml: build spec (preBuild npm ci with offline cache, build
next build, artifacts at .next/**, cache node_modules/.next-cache/.npm).
- .nvmrc: pin Node 20 so Amplify uses the same runtime as local.
- AMPLIFY_DEPLOY.md: first-time walkthrough covering AWS-side setup
(create app, connect GitHub via OAuth/App, branch/auto-detect),
environment variable table with secret-flag guidance, smoke-test via
/healthz and /api/health, optional custom domain + per-PR previews,
cost estimate, and operational notes (cold starts, no static
egress IPs, CloudWatch logs, secret rotation).
- README deploy section: now points at both AMPLIFY_DEPLOY.md and the
existing DEPLOYMENT.md (Render).
