Vulnerability Details

React Router is a router for React. In @⁠remix-run/router version prior to 1.23.2 and react-router 7.0.0 through 7.11.0, React Router (and Remix v1/v2) SPA open navigation redirects originating from loaders or actions in Framework Mode, Data Mode, or the unstable RSC modes can result in unsafe URLs causing unintended javascript execution on the client. This is only an issue if you are creating redirect paths from untrusted content or via an open redirect. There is no impact if Declarative Mode () is being used. This issue has been patched in @⁠remix-run/router version 1.23.2 and react-router version 7.12.0.

Vulnerability Details

React Router is a router for React. In versions 7.0.0 through 7.14.0 and 6.7.0 through 6.30.3, certain URLs passed to the redirect function can trigger an open redirect to an external domain due to path values starting with // being reinterpreted as protocol-relative URLs. The level of impact depends on the validation done by the application prior to returning the redirect. This does not impact applications using Declarative Mode (). This is patched in versions 7.14.1 and 6.30.4.

Vulnerability Details

React Router is a router for React. In versions 6.0.0 through 6.30.1 and 7.0.0 through 7.9.5, an attacker-supplied path can be crafted so that when a React Router application navigates to it via navigate(), , or redirect(), the app performs a navigation/redirect to an external URL. This is only an issue if you are passing untrusted content into navigation paths in your application code. This issue has been patched in versions 6.30.2 and 7.9.6.

Vulnerability Details

React Router is a router for React. In versions 6.4.0 through 7.17.0, if application code was written in a way that allows attacker-supplied input to overwrite certain aspects of errors caught by the SSR process, then it was possible for an attacker to trigger unexpected constructor execution on the client, which would in turn trigger an outbound network request. This is only possible with very specific (and unlikely) application-layer code. Note that this does not impact an application if it is using Declarative Mode. It only impacts Framework Mode and Data Mode applications that perform manual SSR/hydration. This issue has been fixed in version 7.18.0.
