CVE-2026-55685Source published Source updated
React Router is a router for React. In versions 7.0.0 through 7.17.0, the manifest endpoint could be accessed via unauthenticated targeted requests that would put heavy load on the server and slow down response times. This issue has been fixed in version 7.18.0. An unauthenticated attacker can send targeted requests to the manifest endpoint, leading to a denial of service (DoS). This can put a heavy load on the server, significantly slowing down response times and impacting the availability of the application. Repeated, targeted requests to this endpoint place heavy load on the server and can degrade or deny service for other users. Applications using Declarative Mode () or Data Mode (createBrowserRouter/) do not run this server-side code path and are not affected. This mirrors the same…

- Mitigation guidance
- Upgrade to react-router/@remix-run/server-runtime 7.18.0 or later once the fix is packaged in the affected Red Hat product. Where upgrading isn't immediately possible, rate-limiting or restricting access to the manifest endpoint at a reverse proxy or ingress layer can reduce exposure. Products that do not run React Router in Framework Mode (Declarative Mode or Data Mode only) are not affected regardless of the bundled react-router version.
