If you are not a framework author, please contact the authors before submitting._ + + Our goal when recommending a framework is to start developers with a React project that solves common problems like code splitting, data fetching, routing, and HTML generation without any extra work later. We believe this will allow users to get started quickly with React, and scale their app to production. + + While we understand that many frameworks may want to be featured, this page is not a place to advertise every possible React framework or all frameworks that you can add React to. There are many great frameworks that offer support for React that are not listed in our guides. The frameworks we recommend have invested significantly in the React ecosystem, and collaborated with the React team to be compatible with our [full-stack React architecture vision](https://react.dev/learn/creating-a-react-app#which-features-make-up-the-react-teams-full-stack-architecture-vision). + + To be included, frameworks must meet the following criteria: + + - **Free & open-source**: must be open source and free to use. + - **Well maintained**. must be actively maintained, providing bug fixes and improvements. + - **Active community**: must have a sufficiently large and active community to support users. + - **Clear onboarding**: must have clear install steps to install the React version of the framework. + - **Ecosystem compatibility**: must support using the full range of libraries and tools in the React ecosystem. + - **Self-hosting option**: must support an option to self-host applications without losing access to features. + - **Developer experience**. must allow developers to be productive by supporting features like Fast Refresh. + - **User experience**. must provide built-in support for common problems like routing and data-fetching. + - **Compatible with our future vision for React**. React evolves over time, and frameworks that do not align with Reactโ€™s direction risk isolating their users from the main React ecosystem over time.

If you are using any of the above packages please upgrade to any of the fixed versions immediately. + +If your appโ€™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). + +See the [update instructions below](#update-instructions) for how to upgrade to these patches. + +### 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*/} + + + +These instructions have been updated to include the new vulnerabilities: + +- **Denial of Service - High Severity**: [CVE-2025-55184](https://www.cve.org/CVERecord?id=CVE-2025-55184) (CVSS 7.5) +- **Source Code Exposure - Medium Severity**: [CVE-2025-55183](https://www.cve.org/CVERecord?id=CVE-2025-55183) (CVSS 5.3) + +They also include the additional case found, patched, and disclosed as

should be pinned in your `package.json`, and there are no additional steps needed. + +If you are using React Native in a monorepo, you should update _only_ the impacted packages if they are installed: + +- `react-server-dom-webpack` +- `react-server-dom-parcel` +- `react-server-dom-turbopack` + +This is required to mitigate the security advisory, but you do not need to update `react` and `react-dom` so this will not cause the version mismatch error in React Native. + +See [this issue](https://github.com/facebook/react-native/issues/54772#issuecomment-3617929832) for more information.

High vulnerability Denial of Service (CVE-2025-55184), and medium vulnerability Source Code Exposure (CVE-2025-55183) + + +--- + +December 11, 2025 by [The React Team](/community/team) + +--- + + + +Security researchers have found and disclosed two additional vulnerabilities in React Server Components while attempting to exploit the patches in last weekโ€™s critical vulnerability. + +**These new vulnerabilities do not allow for Remote Code Execution.** The patch for React2Shell remains effective at mitigating the Remote Code Execution exploit. + + + +--- + +The new vulnerabilities are disclosed as: + +- **Denial of Service - High Severity**: [CVE-2025-55184](https://www.cve.org/CVERecord?id=CVE-2025-55184) and [CVE-2025-67779](https://www.cve.org/CVERecord?id=CVE-2025-67779) (CVSS 7.5) +- **Source Code Exposure - Medium Severity**: [CVE-2025-55183](https://www.cve.org/CVERecord?id=CVE-2025-55183) (CVSS 5.3) + +We recommend upgrading immediately due to the severity of the newly disclosed vulnerabilities. + + + +#### The patches published earlier are vulnerable. {/*the-patches-published-earlier-are-vulnerable*/} + +If you already updated for the Critical Security Vulnerability last week, you will need to update again. + +If you updated to 19.0.2, 19.1.3, and 19.2.2, [these are incomplete](#additional-fix-published) and you will need to update again. + +Please see [the instructions in the previous post](/blog/2025/12/03/critical-security-vulnerability-in-react-server-components#update-instructions) for upgrade steps. + + + +Further details of these vulnerabilities will be provided after the rollout of the fixes are complete. + +## Immediate Action Required {/*immediate-action-required*/} + +These vulnerabilities are present in the same packages and versions as [CVE-2025-55182](/blog/2025/12/03/critical-security-vulnerability-in-react-server-components). + +This includes versions 19.0.0, 19.0.1, 19.0.2, 19.1.0, 19.1.1, 19.1.2, 19.1.2, 19.2.0, 19.2.1 and 19.2.2 of: + +* [react-server-dom-webpack](https://www.npmjs.com/package/react-server-dom-webpack) +* [react-server-dom-parcel](https://www.npmjs.com/package/react-server-dom-parcel) +* [react-server-dom-turbopack](https://www.npmjs.com/package/react-server-dom-turbopack?activeTab=readme) + +Fixes were backported to versions 19.0.3, 19.1.4, and 19.2.3. If you are using any of the above packages please upgrade to any of the fixed versions immediately. + +As before, if your appโ€™s React code does not use a server, your app is not affected by these vulnerabilities. If your app does not use a framework, bundler, or bundler plugin that supports React Server Components, your app is not affected by these vulnerabilities. + + + +#### Itโ€™s common for critical CVEs to uncover followโ€‘up vulnerabilities. {/*its-common-for-critical-cves-to-uncover-followup-vulnerabilities*/} + +When a critical vulnerability is disclosed, researchers scrutinize adjacent code paths looking for variant exploit techniques to test whether the initial mitigation can be bypassed. + +This pattern shows up across the industry, not just in JavaScript. For example, after [Log4Shell](https://nvd.nist.gov/vuln/detail/cve-2021-44228), additional CVEs ([1](https://nvd.nist.gov/vuln/detail/cve-2021-45046), [2](https://nvd.nist.gov/vuln/detail/cve-2021-45105)) were reported as the community probed the original fix. + +Additional disclosures can be frustrating, but they are generally a sign of a healthy response cycle. + + + +### 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), [@vite/rsc-plugin](https://www.npmjs.com/package/@vitejs/plugin-rsc), and [rwsdk](https://www.npmjs.com/package/rwsdk). + +Please see [the instructions in the previous post](https://react.dev/blog/2025/12/03/critical-security-vulnerability-in-react-server-components#update-instructions) for upgrade steps. + +### Hosting Provider Mitigations {/*hosting-provider-mitigations*/} + +As before, 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. + +### React Native {/*react-native*/} + +For React Native users not using a monorepo or `react-dom`, your `react` version should be pinned in your `package.json`, and there are no additional steps needed. + +If you are using React Native in a monorepo, you should update _only_ the impacted packages if they are installed: + +- `react-server-dom-webpack` +- `react-server-dom-parcel` +- `react-server-dom-turbopack` + +This is required to mitigate the security advisories, but you do not need to update `react` and `react-dom` so this will not cause the version mismatch error in React Native. + +See [this issue](https://github.com/facebook/react-native/issues/54772#issuecomment-3617929832) for more information. + +## High Severity: Denial of Service {/*high-severity-denial-of-service*/} + +**CVEs:** [CVE-2025-55184](https://www.cve.org/CVERecord?id=CVE-2025-55184) and [CVE-2025-67779](https://www.cve.org/CVERecord?id=CVE-2025-67779) +**Base Score:** 7.5 (High) + +Security researchers have discovered that a malicious HTTP request can be crafted and sent to any Server Functions endpoint that, when deserialized by React, can cause an infinite loop that hangs the server process and consumes CPU. 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 creates a vulnerability vector where an attacker may be able to deny users from accessing the product, and potentially have a performance impact on the server environment. + +The patches published today mitigate by preventing the infinite loop. + + + +#### Additional fix published {/*additional-fix-published*/} + +The original fix addressing the DoS in [CVE-2025-55184](https://www.cve.org/CVERecord?id=CVE-2025-55184) was incomplete. + +This left versions 19.0.2, 19.1.3, 19.2.2 vulnerable. Versions 19.0.3, 19.1.4, 19.2.3 are safe. + +We've fixed the additional cases and filed [CVE-2025-67779](https://www.cve.org/CVERecord?id=CVE-2025-67779) for the vulnerable versions. + + + +## Medium Severity: Source Code Exposure {/*low-severity-source-code-exposure*/} + +**CVE:** [CVE-2025-55183](https://www.cve.org/CVERecord?id=CVE-2025-55183) +**Base Score**: 5.3 (Medium) + +A security researcher has discovered that a malicious HTTP request sent to a vulnerable Server Function may unsafely return the source code of any Server Function. Exploitation requires the existence of a Server Function which explicitly or implicitly exposes a stringified argument: + +```javascript +'use server'; + +export async function serverFunction(name) { + const conn = db.createConnection('SECRET KEY'); + const user = await conn.createUser(name); // implicitly stringified, leaked in db + + return { + id: user.id, + message: `Hello, ${name}!` // explicitly stringified, leaked in reply + }} +``` + +An attacker may be able to leak the following: + +```txt +0:{"a":"$@1","f":"","b":"Wy43RxUKdxmr5iuBzJ1pN"} +1:{"id":"tva1sfodwq","message":"Hello, async function(a){console.log(\"serverFunction\");let b=i.createConnection(\"SECRET KEY\");return{id:(await b.createUser(a)).id,message:`Hello, ${a}!`}}!"} +``` + +The patches published today prevent stringifying the Server Function source code. + + + +#### Only secrets in source code may be exposed. {/*only-secrets-in-source-code-may-be-exposed*/} + +Secrets hardcoded in source code may be exposed, but runtime secrets such as `process.env.SECRET` are not affected. + +The scope of the exposed code is limited to the code inside the Server Function, which may include other functions depending on the amount of inlining your bundler provides. + +Always verify against production bundles. + + + +--- + +## Timeline {/*timeline*/} +* **December 3rd**: Leak reported to Vercel and [Meta Bug Bounty](https://bugbounty.meta.com/) by [Andrew MacPherson](https://github.com/AndrewMohawk). +* **December 4th**: Initial DoS reported to [Meta Bug Bounty](https://bugbounty.meta.com/) by [RyotaK](https://ryotak.net). +* **December 6th**: Both issues confirmed by the React team, and the team began investigating. +* **December 7th**: Initial fixes created and the React team began verifying and planning new patch. +* **December 8th**: Affected hosting providers and open source projects notified. +* **December 10th**: Hosting provider mitigations in place and patches verified. +* **December 11th**: Additional DoS reported to [Meta Bug Bounty](https://bugbounty.meta.com/) by Shinsaku Nomura. +* **December 11th**: Patches published and publicly disclosed as [CVE-2025-55183](https://www.cve.org/CVERecord?id=CVE-2025-55183) and [CVE-2025-55184](https://www.cve.org/CVERecord?id=CVE-2025-55184). +* **December 11th**: Missing DoS case found internally, patched and publicly disclosed as [CVE-2025-67779](https://www.cve.org/CVERecord?id=CVE-2025-67779). + +--- + +## Attribution {/*attribution*/} + +Thank you to [Andrew MacPherson (AndrewMohawk)](https://github.com/AndrewMohawk) for reporting the Source Code Exposure, [RyotaK](https://ryotak.net) from GMO Flatt Security Inc and Shinsaku Nomura of Bitforest Co., Ltd. for reporting the Denial of Service vulnerabilities. diff --git a/src/content/blog/index.md b/src/content/blog/index.md index 7fe1b6a0a..2c4890457 100644 --- a/src/content/blog/index.md +++ b/src/content/blog/index.md @@ -10,6 +10,18 @@ title: React ๋ธ”๋กœ๊ทธ
