"details": "## Impact\n\nIt was found that the fix to address [CVE-2025-55184](https://github.com/facebook/react/security/advisories/GHSA-2m3v-v2m8-q956) in React Server Components was incomplete and does not prevent a denial of service attack in a specific case.\n\nWe recommend updating immediately.\n\nThe vulnerability exists in versions 19.0.2, 19.1.3, and 19.2.2 of:\n\n- [react-server-dom-webpack](https://www.npmjs.com/package/react-server-dom-webpack)\n- [react-server-dom-parcel](https://www.npmjs.com/package/react-server-dom-parcel)\n- [react-server-dom-turbopack](https://www.npmjs.com/package/react-server-dom-turbopack?activeTab=readme)\n\nThese issues are present in the patches published on December 11th, 2025.\n\n## Patches\n\nFixes were back ported to versions 19.0.3, 19.1.4, and 19.2.3. \n\nIf you are using any of the above packages please upgrade to any of the fixed versions immediately.\n\nIf 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.\n\n## References\n\nSee the [blog post](https://react.dev/blog/2025/12/11/denial-of-service-and-source-code-exposure-in-react-server-components) for more information and upgrade instructions.",
