    Summary: labbench before 0.46.1 Deserialization of Untrusted Data via read() Pickle Auto-Dispatch

    Details: labbench before 0.46.1 contains a deserialization of untrusted data vulnerability in read() and read_relational() that passes any file with a .p or .pickle extension to pandas.read_pickle based on the extension alone. Attackers who supply a crafted data file or relational data archive can execute arbitrary code when a user loads it with these functions.
