Prior to 4.12.25, with credentials: true and no explicit origin (the default wildcard), the CORS Middleware reflects the request's Origin and sends Access-Control-Allow-Credentials: true. Any site can then make credentialed cross-origin requests and read the responses, exposing cookie-authenticated endpoints to arbitrary origins. This vulnerability is fixed in 4.12.25."

Antes de la versión 4.12.25, con credentials: true y sin un origen explícito (el comodín predeterminado), el Middleware CORS refleja el Origin de la solicitud y envía Access-Control-Allow-Credentials: true. Cualquier sitio puede entonces realizar solicitudes de origen cruzado con credenciales y leer las respuestas, exponiendo puntos finales autenticados por cookie a orígenes arbitrarios. Esta vulnerabilidad se corrige en la versión 4.12.25."
