What is CVE-2020-22083?

The jsonpickle library, up to version 1.4.1, is susceptible to a remote code execution vulnerability triggered during the deserialization of malicious payloads via the decode() function. This flaw allows attackers to exploit the inherent risks of the pickle module, which is known to execute arbitrary code when handling untrusted data. It's critical for developers to recognize the potential dangers associated with using jsonpickle in applications that can process untrusted input.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
