CVE-2021-37704

PhpFastCache is a high-performance backend cache system (packagist package phpfastcache/phpfastcache). In versions before 6.1.5, 7.1.2, and 8.0.7 the `phpinfo()` can be exposed if the `/vendor` is not protected from public access. This is a rare situation today since the vendor directory is often located outside the web directory or protected via server rule (.htaccess, etc). Only the v6, v7 and v8 will be patched respectively in 8.0.7, 7.1.2, 6.1.5. Older versions such as v5, v4 are not longer supported and will **NOT** be patched. As a workaround, protect the `/vendor` directory from public access.

PhpFastCache es un sistema de caché backend de alto rendimiento (paquete phpfastcache/phpfastcache). En versiones anteriores a 6.1.5, 7.1.2 y 8.0.7 la función "phpinfo()" puede quedar expuesto si el directorio "/vendor" no está protegido del acceso público. Esta es una situación rara hoy en día ya que el directorio vendor suele estar situado fuera del directorio web o protegido por medio de una regla del servidor (.htaccess, etc). Sólo las versiones v6, v7 y v8 serán parcheadas respectivamente en las versiones 8.0.7, 7.1.2, 6.1.5. Las versiones más antiguas, como la v5 y la v4, ya no son compatibles y **NO** serán parcheadas. Como solución, proteja el directorio "/vendor" del acceso público
