The advisory says: "Successful exploitation of this vulnerability requires both a producer and a consumer. The producer is a PHP operation that stores state owned by one request in a location PHP can access later in a subsequent request. The consumer is a subsequent PHP operation that reads, frees, branches or otherwise acts on the stale state previously stored by the producer."

The exact words it rests on

Successful exploitation of this vulnerability requires both a producer and a consumer. The producer is a PHP operation that stores state owned by one request in a location PHP can access later in a subsequent request. The consumer is a subsequent PHP operation that reads, frees, branches or otherwise acts on the stale state previously stored by the producer.
