CVE-2026-94545
Published:September 22, 2026
Updated:September 23, 2026
The Node.js ImageResponse implementation in next/og (Next.js 16.2.0 before 16.3.6) passes Satori-generated SVG to sharp. Satori before 0.33.5 does not escape attacker-controlled values placed in SVG content, attributes, or styles, so crafted input is interpreted as SVG markup by the downstream renderer, which can lead to remote code execution. The Edge ImageResponse implementation is not affected.
