Next.js Security Update Oct 14 & Dev Stack Release Log

Executive Summary

• Security watch: Next.js has announced an out-of-band security update for Wednesday, October 14, 2026, covering two Critical and one High severity vulnerabilities in upstream dependencies. Read the official announcement.
• Next.js 16.4.0 is the current stable release (published October 6) and Node.js v26.11.1 landed October 7.
• Astro 7.3.8, SvelteKit 3.0.1 and Nuxt 4.6.1 all shipped within the last week.

• Express 5.3.0, MUI 9.5.0, Motion 14.1.0 and BullMQ 6.3.12 all published on October 9.

Scope note: this audit is built from the npm registry, nodejs.org distribution index and the Next.js blog. GitHub release pages and non-npm sources (Docker Hub, PyPI, Kubernetes, PostgreSQL, Redis, Kafka and others) were not reachable in this run, so those categories are not covered today and no claims are made about them.

Security: Next.js October 14 Update

Vercel's Next.js team says the update addresses three upstream-dependency vulnerabilities (two Critical, one High), two of which were postponed from the September security release due to upstream coordination. Full advisories, affected versions and upgrade instructions will be published with the release. Until then, pin your current version and be ready to upgrade.

# Check what you run today
