HttpCache uses internal headers like X-Body-Eval and X-Body-File to control the restoration of cached responses. The class was initially written with surrogate caching and ESI support in mind (all HTTP calls come from a trusted backend in that scenario). But when used by CachingHttpClient and if an attacker can control the response for a request being made by the CachingHttpClient, remote code execution is possible. This has been fixed in versions 4.4.13 and 5.1.5."},{"lang":"es","value":"En Symfony versiones anteriores a 4.4.13 y 5.1.5, la clase CachingHttpClient del componente HttpClient Symfony se basa en la clase HttpCache para manejar las peticiones. HttpCache utiliza encabezados internos como X-Body-Eval y X-Body-File para controlar la restauración de las respuestas almacenadas en caché. La clase fue inicialmente escrita teniendo en cuenta el almacenamiento en caché sustituto y la compatibilidad con ESI (todas las llamadas HTTP provienen de un backend confiable en ese escenario).
