Security Risks of Using Pickle for Deserialization in Python
This article comprehensively introduces the concepts of serialization and deserialization in Python, as well as the application of the Pickle module in this process. At the same time, it elaborates in detail on the principles of deserialization attacks and demonstrates the ways that attackers may use through specific code examples. Finally, we discussed the principles and specific methods of preventing Pickle deserialization attacks, including restricting deserialization types and using more secure serialization modules. It is hoped that through the introduction of this article, everyone can have a deeper understanding of deserialization attacks and take effective preventive measures in actual programming to ensure the security of the system. If you have any questions or suggestions about the content of this article, you are welcome to discuss them in the comment section.
