Executive Snapshot Your application security assumes the underlying web framework is safe. A CVSS 10.0 flaw in React Server Components now allows unauthenticated remote code execution across any deployment running RSC, affecting 39% of cloud environments according to Wiz.

Signal Enterprises hardened application logic while trusting that React and Next.js handled serialization safely; that trust just became the entry point for server takeover without credentials.

Strategic Implication Your security investments protected the application layer while the framework beneath it offered attackers a master key.

Action Inventory all React and Next.js deployments across your cloud environments today. Upgrade react-server-dom packages and Next.js to patched versions now. Alert engineering teams that any application supporting React Server Components is exposed until remediation is complete this week.
