If you are using any of the above packages please upgrade to any of the fixed versions immediately. + +If your app’s React code does not use a server, your app is not affected by this vulnerability. If your app does not use a framework, bundler, or bundler plugin that supports React Server Components, your app is not affected by this vulnerability. + +### Affected frameworks and bundlers {/*affected-frameworks-and-bundlers*/} + +Some React frameworks and bundlers depended on, had peer dependencies for, or included the vulnerable React packages. The following React frameworks & bundlers are affected: [next](https://www.npmjs.com/package/next), [react-router](https://www.npmjs.com/package/react-router), [waku](https://www.npmjs.com/package/waku), [@parcel/rsc](https://www.npmjs.com/package/@parcel/rsc), [@vitejs/plugin-rsc](https://www.npmjs.com/package/@vitejs/plugin-rsc), and [rwsdk](https://www.npmjs.com/package/rwsdk). + +We will update this post with upgrade instructions on how to upgrade as they become available. + +### Hosting Provider Mitigations {/*hosting-provider-mitigations*/} + +We have worked with a number of hosting providers to apply temporary mitigations. + +You should not depend on these to secure your app, and still update immediately. + +### Vulnerability overview {/*vulnerability-overview*/} + +[React Server Functions](https://react.dev/reference/rsc/server-functions) allow a client to call a function on a server. React provides integration points and tools that frameworks and bundlers use to help React code run on both the client and the server. React translates requests on the client into HTTP requests which are forwarded to a server. On the server, React translates the HTTP request into a function call and returns the needed data to the client. + +An unauthenticated attacker could craft a malicious HTTP request to any Server Function endpoint that, when deserialized by React, achieves remote code execution on the server. Further details of the vulnerability will be provided after the rollout of the fix is complete. + +## Update Instructions {/*update-instructions*/} + +### Next.js {/*update-next-js*/} + +All users should upgrade to the latest patched version in their release line: + +```bash +npm install next@15.0.5 // for 15.0.x +npm install next@15.1.9 // for 15.1.x +npm install next@15.2.6 // for 15.2.x +npm install next@15.3.6 // for 15.3.x +npm install next@15.4.8 // for 15.4.x +npm install next@15.5.7 // for 15.5.x +npm install next@16.0.7 // for 16.0.x +``` + +If you are on Next.js 14.3.0-canary.77 or a later canary release, downgrade to the latest stable 14.x release: + +```bash +npm install next@14 +``` + +See the [Next.js changelog](https://nextjs.org/blog/CVE-2025-66478) for more info. + +### React Router {/*update-react-router*/} + +If you are using React Router's unstable RSC APIs, you should upgrade the following package.json dependencies if they exist: + +```bash +npm install react@latest +npm install react-dom@latest +npm install react-server-dom-parcel@latest +npm install react-server-dom-webpack@latest +npm install @vitejs/plugin-rsc@latest +``` + +### Expo {/*expo*/} + +Upgrade to the latest `react-server-dom-webpack`: + +```bash +npm install react@latest react-dom@latest react-server-dom-webpack@latest +``` + +### Redwood SDK {/*update-redwood-sdk*/} + +Ensure you are on rwsdk>=1.0.0-alpha.0 + +For the latest beta version: + +```bash +npm install rwsdk@latest +``` + +Upgrade to the latest `react-server-dom-webpack`: + +```bash +npm install react@latest react-dom@latest react-server-dom-webpack@latest +``` + +See [Redwood docs](https://docs.rwsdk.com/migrating/) for more migration instructions. + +### Waku {/*update-waku*/} + +Upgrade to the latest `react-server-dom-webpack`: + +```bash +npm install react@latest react-dom@latest react-server-dom-webpack@latest waku@latest +``` + +See [Waku announcement](https://github.com/wakujs/waku/discussions/1823) for more migration instructions. + +### `@vitejs/plugin-rsc` {/*vitejs-plugin-rsc*/} + +Upgrade to the latest RSC plugin: + +```bash +npm install react@latest react-dom@latest @vitejs/plugin-rsc@latest +``` + +### `react-server-dom-parcel` {/*update-react-server-dom-parcel*/} + +Update to the latest version: + + ```bash + npm install react@latest react-dom@latest react-server-dom-parcel@latest + ``` + +### `react-server-dom-turbopack` {/*update-react-server-dom-turbopack*/} + +Update to the latest version: + + ```bash + npm install react@latest react-dom@latest react-server-dom-turbopack@latest + ``` + +### `react-server-dom-webpack` {/*update-react-server-dom-webpack*/} + +Update to the latest version: + + ```bash +npm install react@latest react-dom@latest react-server-dom-webpack@latest + ``` + +## Timeline {/*timeline*/} + +* **November 29th**: Lachlan Davidson reported the security vulnerability via [Meta Bug Bounty](https://bugbounty.meta.com/). +* **November 30th**: Meta security researchers confirmed and began working with the React team on a fix. +* **December 1st**: A fix was created and the React team began working with affected hosting providers and open source projects to validate the fix, implement mitigations and roll out the fix +* **December 3rd**: The fix was published to npm and the publicly disclosed as CVE-2025-55182. + +## Attribution {/*attribution*/} + +Thank you to [Lachlan Davidson](https://github.com/lachlan2k) for discovering, reporting, and working to help fix this vulnerability. diff --git a/src/content/blog/index.md b/src/content/blog/index.md index 0a3e02871b..0d9325dbb6 100644 --- a/src/content/blog/index.md +++ b/src/content/blog/index.md @@ -11,7 +11,17 @@ title: React Blog
