What changed

next and eslint-config-next move from 16.3.8 to 16.4.5. No content or code changes.

Sources

Next.js 16.0.0 to 16.4.0 is affected by:

The site uses none of next/image, use cache or server actions, so real exposure looks low. But /_next/image responds on the live site, so this upgrades anyway.

After the upgrade, npm audit --omit=dev reports 0 vulnerabilities. npm run lint, npm run typecheck, npm test (17 tests) and npm run build all pass locally, and the build still prerenders every route.

Checklist

  • Every new or changed claim links a primary source. (No content claims changed.)
  • If I changed a status, the evidence meets the rules in content/contribute.md. (No status changed.)
  • I only changed last_verified on pages where I rechecked every claim. (None changed.)
  • Plain words, no em dashes.

Generated by Claude Code

Next.js 16.0.0 to 16.4.0 is affected by GHSA-2464-fhr4-w9xw (remote code
execution in the image optimization API with SVG files), GHSA-673q-mjm6-r5xr
(remote code execution in `use cache` functions returning typed arrays) and
GHSA-p3m5-59mp-jv5r (denial of service through server actions). The site uses
none of next/image, `use cache` or server actions, but /_next/image answers on
the live site, so upgrade. eslint-config-next moves with it.
