CRITICAL 9.8EPSS 6.42%
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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
