Background
jsonpickle is a Python library used for serializing and deserializing complex Python objects to and from JSON. It provides a convenient way to store and transfer data between different systems. However, jsonpickle versions up to 1.4.1 are vulnerable to remote code execution during the deserialization process. This vulnerability can be exploited by an attacker to execute arbitrary code on the target system.
Vulnerability Detail
The vulnerability, identified as CVE-2020-22083, occurs due to the insecure deserialization of a malicious payload through the decode() function in jsonpickle. This behavior is documented but can lead to unexpected code execution. The pickle module, which jsonpickle relies on, is known for its ability to execute arbitrary code and should not be used with untrusted data. An attacker can craft a specially crafted payload that, when deserialized by jsonpickle, triggers the execution of arbitrary code on the target system. This can result in a complete compromise of the system, leading to unauthorized access, data theft, or further exploitation.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a workaround, it is recommended to avoid using jsonpickle with untrusted data. If possible, consider using alternative serialization libraries that do not rely on pickle, or implement strict input validation and sanitization when deserializing JSON data. By carefully validating and filtering input, the risk of code execution can be reduced.
Conclusion
The remote code execution vulnerability in jsonpickle can have severe consequences if exploited. It is crucial to upgrade to a patched version of jsonpickle (1.4.2 or higher) and keep all dependencies up to date. Additionally, avoid using jsonpickle with untrusted data and implement strict input validation to mitigate the risk of code execution.
