| Description: | | Celery is a simple, flexible, and reliable distributed system that processes a large number of messages while providing the tools needed to operate and maintain such a system. It is a task queue focused on real-time processing and also supports task scheduling.In Celery <4.0 version, Pickle is used by default for serialized task messages. When the queue service(e.g. Redis/RabbitMQ/RocketMQ ) used has an unauthorized access problem, the Pickle deserialization vulnerability can be used to execute arbitrary code. |
