GHSA-8X6R-G9MW-2R78 React Router vulnerable to DoS via unbounded path expansion in __manifest endpoint

There exists a potential DOS attack vector in React Router Framework Mode applications as well as Remix v2.10.0 - 2.17.4. Certain requests can be crafted to consume disproportionate resources on the server, resulting in response time degredation and/or service unavailability for end users. !NOTE...

React Router's vendored turbo-stream v2 allows arbitrary constructor invocation via TYPE_ERROR deserialization leading to Unauth RCE

When using React Router v7 in Framework Mode, there exists a combination of steps that could potentially allow unauthorized RCE through external requests. This first requires the application code to have an existing prototype pollution vulnerability. This can be leveraged into a 2-step attack in...
