## Description

Hugging Face Datasets through 5.1.0 contains an insecure deserialization vulnerability that allows attackers to execute arbitrary Python code by crafting a malicious pickle file loaded through the deprecated pandas packaged builder. Attackers can supply a pickle-backed dataset that is processed by Pandas.\_generate\_tables via pandas.read\_pickle() without validation, so when a victim calls datasets.load\_dataset("pandas", data\_files=...), the embedded \_\_reduce\_\_ payload executes code with the victim process's privileges.
