React Flight Protocol Rce Vulnerability Cve 2025 55182 And Cve 2025 The table above outlines the components and software versions impacted by cve 2025 55182 (react2shell). the vulnerability primarily affects environments that use react server components (rsc) and rely on the react flight protocol for server to client communication. React server components bring a lot of power to web development, but sometimes power comes with risk. in early 2025, a major vulnerability—cve 2025 55182—was discovered in several versions of react server components (v19 through v19.2.). this bug exposes servers to pre authentication remote code execution (rce) via unsafe deserialization.
Cve 2025 55182 Critical Rce In React Server Components Learn how cve 2025 55182 (cvss 10.0) enables critical rce in the rsc ecosystem, why it happened, and how the public exploit works against react’s server side handling. Cve 2025 55182 represents a high impact, low friction attack path against modern react server components deployments. rapid patching combined with layered defender monitoring and waf protections provides the strongest short term and long term risk reduction strategy. 👉 cve 2025–55182, nicknamed react2shell, enables unauthenticated remote code execution (rce) against servers running vulnerable react and next.js applications — with a cvss score of. Cve 2025 55182 is an unsafe deserialization vulnerability in rsc. an unauthenticated, remote attacker could exploit this vulnerability by sending a specially crafted payload to a vulnerable react server function endpoint. successful exploitation could result in remote code execution on the server.

Cve 2025 55182 is an unsafe deserialization vulnerability in rsc. an unauthenticated, remote attacker could exploit this vulnerability by sending a specially crafted payload to a vulnerable react server function endpoint. successful exploitation could result in remote code execution on the server. React server components (rsc) let react render components on the server instead of the browser. this improves performance and allows react to handle heavy logic before delivering the final html to the client. Cve 2025 55182 is a critical react server components rce flaw under active exploitation. learn how it works, who is affected, and how to protect your applications. Cve 2025 55182 detail description a pre authentication remote code execution vulnerability exists in react server components versions 19.0.0, 19.1.0, 19.1.1, and 19.2.0 including the following packages: react server dom parcel, react server dom turbopack, and react server dom webpack. Successful exploitation of cve 2025 55182 allows a remote unauthenticated attacker to execute arbitrary code on an affected server via malicious http requests. the vulnerability affects react applications that support react server components.
