Submit #579157: erdogant pypickle 1.1.5 Insecure Deserialization

In the repository https://github.com/erdogant/pypickle, the function load() in pypickle.py uses Python’s pickle.load() to deserialize data from a file without validating or sanitizing the input. If an attacker supplies a malicious pickle file, they can execute arbitrary code when the file is loaded, resulting in a Remote Code Execution (RCE) vulnerability.

This occurs because pickle.load() is inherently unsafe for loading untrusted data, as it can deserialize and invoke arbitrary Python objects, including system calls.
