Trend Micro researchers have previously published a blog on what organizations need to know about the actively exploited CVE-2025-55182, which is a critical (CVSS 10.0) pre-authentication remote code execution vulnerability affecting React Server Components (RSC) used in React.js, Next.js, and related frameworks.

RSC communicate between client and server using a serialization protocol called “React Flight.” This protocol enables streaming of complex data structures that mirror the React component tree, allowing UIs to render progressively while awaiting backend responses.
