Symfony collectionCascaded and collectionCascadedDeeply fields security bypass
When using the Validator component, if Symfony\\Component\\Validator\\Mapping\\Cache\\ApcCache is enabled (or any other cache implementing Symfony\\Component\\Validator\\Mapping\\Cache\\CacheInterface), some information is lost during serialization (the collectionCascaded and the collectionCascadedDeeply fields).
As a consequence, arrays or traversable objects stored in fields using the @Valid constraint are not traversed by the validator as soon as the validator configuration is loaded from the cache.
