This is especially helpful if you use Netlify Drop to publish or update your project and don’t use Git workflows to sychronize versions of your project. Syncing changes helps you and your whole team build and publish faster. ## How it works For example, let’s say you used Netlify Drop to publish your project without setting up a Git workflow. Next, you decide to use Agent Runners to add a new landing page. You also start an agent run to update your project’s footer and publish the new footer. Your agent run for the new landing page doesn’t include the footer changes yet. To get these updates, start a **sync run** from the Agent Runners dashboard. This will apply all new updates from the live production version of your project. Now when you publish your landing page updates, you’ll get the updated footer as well. Syncing changes with Agent Runners enables smoother shipping with several agent runs and with multiple [team members](https://docs.netlify.com/manage/accounts-and-billing/team-management/manage-team-members/#add-new-team-members) working on the same project.

Previously, projects without a build step couldn’t use Agent Runners. ### Improved diff view performance By default, the diff view now loads only the first 50 changed files with an option to load more. This improves performance for large projects. ## Feedback welcome Keep sharing your product feedback about Agent Runners in the feedback form at the bottom of our [Agent Runners docs page](https://docs.netlify.com/build/build-with-ai/agent-runners/overview/). And don’t forget that while you can run multiple agent runs and do other work while they run, you can also [play a Netlify game](https://www.netlify.com/changelog/2026-01-08-agent-runner-games/) while you wait for the agent to finish.

A malicious payload can cause memory exhaustion or excessive CPU consumption. Next.js has also disclosed two unrelated medium-severity CVEs ([CVE-2025-59471](https://www.cve.org/CVERecord?id=CVE-2025-59471), [CVE-2025-59472](https://www.cve.org/CVERecord?id=CVE-2025-59472)) patched in the same releases. Here’s what Netlify customers need to know. ## Impact on Netlify Nominally, this is a server-side DoS vulnerability. However, **on Netlify this has minimal impact**: our autoscaling serverless architecture means that a malicious request resulting in a crashed or hung function does not affect other requests. However, active exploitation could increase your function costs. ## Affected frameworks All RSC frameworks are affected: - **Next.js** (see version table below) - React Router 7 (if using RSC preview) - Waku - `@parcel/rsc` - `@vitejs/plugin-rsc` Astro, Gatsby, and Remix are not affected. ### React affected versions See the [React blog post](https://react.dev/blog/2025/12/11/denial-of-service-and-source-code-exposure-in-react-server-components) for full details. Affected versions Fixed in 19.0.0–19.0.3 19.0.4 19.1.0–19.1.4 19.1.5 19.2.0–19.2.3 19.2.4 ### Next.js affected versions See the [Next.js advisory](https://github.com/vercel/next.js/security/advisories/GHSA-h25m-26qc-wcjf) for full details. Affected versions Fixed in 13.3.0+ EOL - no fix 14.x EOL - no fix 15.0.0–15.0.7 15.0.8 15.1.0–15.1.10 15.1.11 15.2.0–15.2.8 15.2.9 15.3.0–15.3.8 15.3.9 15.4.0–15.4.10 15.4.11 15.5.0–15.5.9 15.5.10 15.x canaries 15.6.0-canary.61 16.0.0–16.0.10 16.0.11 16.1.0–16.1.4 16.1.5 16.x canaries 16.2.0-canary.9 ## What should I do? If any of your projects are using an affected version, we recommend upgrading as soon as possible to a patched release. For Next.js 13.x and 14.x users: patches are not planned for these versions. Consider upgrading to Next.js 15.x or 16.x. Note that any publicly available deploy previews and branch deploys may remain vulnerable until they are [automatically deleted](https://docs.netlify.com/deploy/manage-deploys/manage-deploys-overview/#automatic-deploy-deletion). Consider [deleting these deploys manually](https://docs.netlify.com/deploy/manage-deploys/manage-deploys-overview/#manual-deploy-deletion-through-the-netlify-ui). ## Resources - [React CVE-2026-23864](https://www.cve.org/CVERecord?id=CVE-2026-23864) - [React blog post](https://react.dev/blog/2025/12/11/denial-of-service-and-source-code-exposure-in-react-server-components) - [Next.js security advisory](https://github.com/vercel/next.js/security/advisories/GHSA-h25m-26qc-wcjf) [Permalink to Security Update: DoS vulnerability in Next.js and React Server Components Permalink](/changelog/2026-01-26-react-nextjs-dos-vulnerability/) - [ ## Security Update: Multiple vulnerabilities in React Router and Remix ](/changelog/2026-01-15-react-router-remix-security-vulnerabilities/) January 19, 2026 - [security](/changelog/tag/security/) - [remix](/changelog/tag/remix/) The React Router team has disclosed six security vulnerabilities affecting React Router and Remix. Here’s what Netlify customers need to know. ## Vulnerabilities Vulnerability Remix versions React Router versions & modes [CVE-2025-61686](https://github.com/remix-run/react-router/security/advisories/GHSA-9583-h5hc-x8cw) - Path traversal ≤2.17.1 7.0.0–7.9.3 All modes [CVE-2025-68470](https://github.com/remix-run/react-router/security/advisories/GHSA-9jcx-v3wj-wh4m) - Open redirect \- 6.0.0–6.30.1, 7.0.0–7.9.5 All modes [CVE-2026-22030](https://github.com/remix-run/react-router/security/advisories/GHSA-h5cw-625j-3rxh) - CSRF ≤2.17.2 7.0.0–7.11.0 Framework only [CVE-2025-59057](https://github.com/remix-run/react-router/security/advisories/GHSA-3cgp-3xvw-98x8) - Meta XSS 1.15.0–2.17.0 7.0.0–7.8.2 Framework only [CVE-2026-22029](https://github.com/remix-run/react-router/security/advisories/GHSA-2w69-qvjg-hvjx) - Redirect XSS ≤2.17.3 6.0.0–6.30.2, 7.0.0–7.11.0 Framework, Data [CVE-2026-21884](https://github.com/remix-run/react-router/security/advisories/GHSA-8v8x-cx79-35w7) - ScrollRestoration XSS ≤2.17.2 7.0.0–7.11.0 Framework only ## Impact on Netlify ### CVE-2025-61686 (path traversal) This vulnerability affects `@react-router/node`, `@remix-run/node`, and `@remix-run/deno`. These packages are not used on Netlify, therefore **Netlify projects are not affected**. ### CVE-2025-68470 (open redirect) Apps with unsafe uses of React Router navigation APIs may be hijacked to redirect to arbitrary origins. **Regardless of hosting provider, all apps constructing paths from untrusted user input may be vulnerable.** ### CVE-2026-22030 (CSRF) Actions and experimental RSC Server Functions can be triggered by cross-origin form submissions, allowing an attacker to execute actions on behalf of authenticated users. **Regardless of hosting provider, all apps may be vulnerable.** ### CVE-2025-59057, CVE-2026-22029, and CVE-2026-21884 (XSS) These are cross-site scripting (XSS) vulnerabilities. For example, in CVE-2026-22029 actions and experimental RSC Server Functions performing a redirect to a path constructed from untrusted user input may be hijacked to execute arbitrary JavaScript in the browser. **Regardless of hosting provider, all apps passing untrusted data into certain APIs may be vulnerable.** (The Remix team has left this intentionally vague.) ## What should I do? If any of your projects are using any affected version listed above, we strongly recommend upgrading as soon as possible to patched releases: - `react-router` 7.12.0 or later (for React Router 7.x) - `react-router` 6.30.2 or later (for React Router 6.x) - `@remix-run/react` 2.17.4 or later - `@remix-run/server-runtime` 2.17.4 or later Note that any publicly available deploy previews and branch deploys may remain vulnerable until they are [automatically deleted](https://docs.netlify.com/deploy/manage-deploys/manage-deploys-overview/#automatic-deploy-deletion). Consider [deleting these deploys manually](https://docs.netlify.com/deploy/manage-deploys/manage-deploys-overview/#manual-deploy-deletion-through-the-netlify-ui). [Permalink to Security Update: Multiple vulnerabilities in React Router and Remix Permalink](/changelog/2026-01-15-react-router-remix-security-vulnerabilities/) - [ ## Security Update: DoS vulnerability in Node.js ](/changelog/2026-01-16-nodejs-async-hooks-dos-vulnerability/) January 16, 2026 - [security](/changelog/tag/security/) - [functions](/changelog/tag/functions/) The Node.js team has released a [security update addressing a denial-of-service vulnerability](https://nodejs.org/en/blog/vulnerability/january-2026-dos-mitigation-async-hooks) affecting applications that use `async_hooks` (including in dependencies). Here’s what Netlify customers need to know. ## Vulnerability When `async_hooks` are enabled on certain versions of Node.js, a stack overflow causes the Node.js process to exit immediately rather than throw a catchable error. This bypasses `try-catch` blocks and uncaught exception handlers entirely. A malicious actor could send a crafted payload to crash a server. Note that many common tools and frameworks use `async_hooks` under the hood, notably APM and tracing tools (e.g. DataDog, NewRelic, OpenTelemetry) as well as Next.js App Router and other React Server Components implementations. You can find [more details on that here](https://nodejs.org/en/blog/vulnerability/january-2026-dos-mitigation-async-hooks#important-react-and-nextjs-impact-by-version). ## Impact on Netlify This is a server-side denial-of-service (DoS) vulnerability. **On Netlify, this has minimal impact**: our autoscaling serverless architecture means that a malicious request resulting in a crashed or hung function does not affect other requests. However, active exploitation could increase your cold starts and your function costs. Note that Node.js used during your project’s _build_ is not impacted at all. ## What should I do? If you have [opted your Netlify Functions into Node.js 18](https://docs.netlify.com/build/functions/optional-configuration/?fn-language=js&data-tab=TypeScript#nodejs-version-for-runtime), we **recommend upgrading to Node.js 20 or later**. Node.js 18 reached end-of-life in April 2025 and thus will not be patched. Otherwise, there is **no action for you to take**. Although this CVE’s impact to Netlify sites is limited, deployed Netlify Functions will be updated to patched Node.js versions automatically on a rolling basis. For completeness, please note that [the Node.js version used during your project’s _build_](https://docs.netlify.com/build/configure-builds/manage-dependencies/#nodejs-and-javascript) is not relevant to this CVE. There is no action for you to take and this will not be automatically patched. ## Resources - [Node.js security release announcement](https://nodejs.org/en/blog/vulnerability/january-2026-dos-mitigation-async-hooks) - [Netlify Functions Node.js version configuration](https://docs.netlify.com/build/functions/optional-configuration/?fn-language=js&data-tab=TypeScript#nodejs-version-for-runtime) [Permalink to Security Update: DoS vulnerability in Node.js Permalink](/changelog/2026-01-16-nodejs-async-hooks-dos-vulnerability/) [Previous page](/changelog/page/8) [Next page](/changelog/page/10)
