CRITICAL · CVSS 3.1 · EPSS 3.6% (pctl 89)
In your normal cycle
Critical by CVSS (9.8), but no sign of active exploitation.
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
