Next.js Ships Out-of-Band Patch for Two Critical RCE Flaws in Caching and SVG Processing
Summary: Next.js released an out-of-band update on October 14 fixing two critical unauthenticated remote code execution flaws and one high-severity denial-of-service flaw, in versions 16.4.1 and 15.5.28. One code-execution flaw is in React Server Components, affecting react-server-dom-webpack, react-server-dom-parcel, and react-server-dom-turbopack versions 19.0.0 through 19.3.0, and the other is a memory bug in librsvg reached through the bundled sharp package on glibc-based Linux; Vercel rated both critical at CVSS 9.5.
Bottom line: As of October 15 the use cache and Server Actions advisories had no CVE and did not appear in the npm advisory feed npm audit uses, so your dependency scanners may stay silent on two of the three flaws. On version 15, upgrading to 15.5.28 can leave the affected sharp 0.34.x in place, so check with npm ls sharp and move to 0.35.5 or later.
