Vulnerability CVE-2020-22083
Published: 2020-12-17

Description:
** DISPUTED ** jsonpickle through 1.4.1 allows remote code execution during deserialization of a malicious payload through the decode() function. Note: It has been argued that this is expected and clearly documented behaviour. pickle is known to be capable of causing arbitrary code execution, and must not be used with un-trusted data.

Type:

CWE-502

 (Deserialization of Untrusted Data)
