React Server Components Pre Authentication Remote Code Execution In React Ser Cve 2025 55182

Remote Code Execution Vulnerability In React Server Components Cve 2025 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. Even if your app does not implement any react server function endpoints it may still be vulnerable if your app supports react server components. this vulnerability was disclosed as cve 2025 55182 and is rated cvss 10.0.

React Server Components Security Flaw Risks Unauthenticated Remote Cve 2025 55182 (also referred to as react2shell and includes cve 2025 66478, which was merged into it) is a critical pre authentication remote code execution (rce) vulnerability affecting react server components, next.js, and related frameworks. A pre authentication remote code execution vulnerability (cve 2025 55182) has been disclosed in react server components versions 19.0.0, 19.1.0, 19.1.1, and 19.2.0 including the following packages: this vulnerability has been rated as a cvss 10.0. Meta react server components contains a remote code execution vulnerability that could allow unauthenticated remote code execution by exploiting a flaw in how react decodes payloads sent to react server function endpoints. 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 of user supplied data.
