8 Next.js patches critical AVIF and Windows vulnerabilities allowing unauthenticated RCE¶
Vercel released critical security patches for two remote-code-execution vulnerabilities in Next.js. The first (CVE-2026-75604, CVSS 9.0) is a Windows-specific path traversal flaw; the second (GHSA-2xp9-vwfh-vxw4, CVSS 9.5) is a heap buffer overflow triggered by malicious AVIF images. Patches were released August 25, 2026 in Next.js 15.5.24 and 16.3.3; Vercel stated no workaround exists for affected Windows-hosted applications.
