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 is a modern architecture where UI components run on the server instead of the browser, reducing JavaScript sent to clients. 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. The sum of which can be called the RSC payload. Think of it as an RPC-over-HTTP mechanism where clients send “chunks” of serialized data to Server Functions.
