CVE-2026-119347
Published:November 03, 2026
Updated:November 04, 2026
<!-- https://linear.app/vercel/issue/NSEC-438 --> On self-hosted deployments, the Next.js image optimizer (`/_next/image`) can be made to process an attacker-supplied SVG even when SVG support is disabled with `dangerouslyAllowSVG: false` (the default). This reaches an SVG parser the application intended to keep disabled, increasing exposure to denial of service and SVG decoder vulnerabilities.
