CVE-2025-43864
HighSummary
React Router, używany w aplikacjach React, ma podatność od wersji 7.2.0 do 7.5.2, która pozwala na wymuszenie przełączenia aplikacji w tryb SPA poprzez dodanie nagłówka do żądania. W przypadku aplikacji korzystających z SSR, wymuszenie tego trybu prowadzi do błędu, który całkowicie psuje stronę.
Risk Assessment
W przypadku zastosowania systemu cache, odpowiedź zawierająca błąd może zostać zbuforowana, co prowadzi do zanieczyszczenia pamięci podręcznej i poważnie wpływa na dostępność aplikacji.
Recommendation
Zaleca się aktualizację React Router do wersji 7.5.2, aby usunąć tę podatność i zapobiec problemom z dostępnością aplikacji.

Original NVD description (English source)
React Router is a router for React. Starting in version 7.2.0 and prior to version 7.5.2, it is possible to force an application to switch to SPA mode by adding a header to the request. 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. This issue has been patched in version 7.5.2.
