CVE-2026-42342 in react-router
Sumário
de MITRE • 03/06/2026
React Router is a router for React. In versions 7.0.0 through 7.14.x of react-router and versions 2.10.0 through 2.17.4 of @remix-run/server-runtime, certain crafted requests can consume disproportionate server resources via unbounded path expansion in the __manifest endpoint, resulting in response time degradation and/or service unavailability for end users. This affects React Router Framework Mode applications as well as Remix applications. This does not impact applications using Declarative Mode (``) or Data Mode (`createBrowserRouter/`). This is patched in react-router version 7.15.0 and @remix-run/server-runtime version 2.17.5.
