CVE-2020-13092
9.8
CRITICAL · CVSS 3.1 · EPSS 3.4% (pctl 88)
In your normal cycle
Critical by CVSS (9.8), but no sign of active exploitation.
Description
scikit-learn (aka sklearn) through 0.23.0 can unserialize and execute commands from an untrusted file that is passed to the joblib.load() function, if __reduce__ makes an os.system call. NOTE: third parties dispute this issue because the joblib.load() function is documented as unsafe and it is the user's responsibility to use the function in a secure manner
