CVE-2020-13091
pandas through 1.0.3 can unserialize and execute commands from an untrusted file that is passed to the read_pickle() function, if __reduce__ makes an os.system call.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
pandas through 1.0.3 can unserialize and execute commands from an untrusted file that is passed to the read_pickle() function, if __reduce__ makes an os.system call. NOTE: third parties dispute this issue because the read_pickle() function is documented as unsafe and it is the user's responsibility to use the function in a secure manner
