If the application uses SSR and is forced to switch to SPA, this causes an error that completely corrupts the page. If a cache system is in place, this allows the response containing the error to be cached, resulting in a cache poisoning that strongly impacts the availability of the application.\n\n## Details\nThe vulnerable header is `X-React-Router-SPA-Mode`; adding it to a request sent to a page/endpoint using a loader throws an error. Here is [the vulnerable code](https://github.com/remix-run/react-router/blob/e6c53a0130559b4a9bd47f9cf76ea5b08a69868a/packages/react-router/lib/server-runtime/server.ts#L407) :\n\n<img width=\"672\" alt=\"Capture d’écran 2025-04-07 à 08 28 20\" src=\"https://github.com/user-attachments/assets/0a0e9c41-70fd-4dba-9061-892dd6797291\" />\n\nTo use the header, React-router must be used in Framework mode, and for the attack to be possible the target page must use a loader.\n\n## Steps to reproduce \nVersions used for our PoC: \n- \"@react-router/node\": \"^7.5.0\",\n- \"@react-router/serve\": \"^7.5.0\",\n- \"react\": \"^19.0.0\"\n- \"react-dom\": \"^19.0.0\"\n- \"react-router\": \"^7.5.0\"\n\n1. Install React-Router with its default configuration in Framework mode (https://reactrouter.com/start/framework/installation)\n2. Add a simple page using a loader (example: `routes/ssr`)\n\n\n\n3. Send a request to the endpoint using the loader (`/ssr` in our case) adding the following header:\n```\nX-React-Router-SPA-Mode: yes\n```\n\nNotice the difference between a request with and without the header;\n\n**Normal request**\n\n\n**With the header**\n\n\n\n## Impact\nIf a system cache is in place, it is possible to poison the response by completely altering its content (*by an error message*), strongly impacting its availability, making the latter impractical via a cache-poisoning attack.\n\n## Credits\n- Rachid Allam (zhero;)\n- Yasser Allam (inzo_)", "references": [ {

data by adding a header to the request. This allows to completely spoof its contents and modify all the values of the data object passed to the HTML. Latest versions are impacted.\n\n## Details\nThe vulnerable header is `X-React-Router-Prerender-Data`, a specific JSON object must be passed to it in order for the spoofing to be successful as we will see shortly. Here is [the vulnerable code](https://github.com/remix-run/react-router/blob/e6c53a0130559b4a9bd47f9cf76ea5b08a69868a/packages/react-router/lib/server-runtime/routes.ts#L87) :\n\n<img width=\"776\" alt=\"Capture d’écran 2025-04-07 à 05 36 58\" src=\"https://github.com/user-attachments/assets/c95b0b33-15ce-4d30-9f5e-b10525dd6ab4\" />\n\nTo use the header, React-router must be used in Framework mode, and for the attack to be possible the target page must use a loader.\n\n## Steps to reproduce \nVersions used for our PoC: \n- \"@react-router/node\": \"^7.5.0\",\n- \"@react-router/serve\": \"^7.5.0\",\n- \"react\": \"^19.0.0\"\n- \"react-dom\": \"^19.0.0\"\n- \"react-router\": \"^7.5.0\"\n\n1.

In our case the page is called `/ssr`:\n\n\n\nWe access it by adding the suffix `.data` and retrieve the data object, needed for the header:\n\n\n\n4. Send your request by adding the `X-React-Router-Prerender-Data` header with the previously retrieved object as its value. You can change any value of your `data` object (do not touch the other values, the latter being necessary for the object to be processed correctly and not throw an error):\n\n\n\nAs you can see, all values have been changed/overwritten by the values provided via the header. \n\n## Impact\nThe impact is significant, if a cache system is in place, it is possible to poison a response in which all of the data transmitted via a loader would be altered by an attacker allowing him to take control of the content of the page and modify it as he wishes via a cache-poisoning attack. This can lead to several types of attacks including potential stored XSS depending on the context in which the data is injected and/or how the data is used on the client-side.\n\n## Credits\n- Rachid
