      "value": "In Symfony before versions 4.4.7 and 5.0.7, when a `Response` does not contain a `Content-Type` header, affected versions of Symfony can fallback to the format defined in the `Accept` header of the request, leading to a possible mismatch between the response's content and `Content-Type` header. When the response is cached, this can prevent the use of the website by other users. This has been patched in versions 4.4.7 and 5.0.7."

Cuando la respuesta es almacenada en cach\u00e9, esto puede impedir el uso del sitio web por otros usuarios. Esto ha sido parcheado en las versiones 4.4.7 y 5.0.7."
