Picklescan versions prior to 0.0.29 fail to detect malicious pickle files that exploit the built-in Python function idlelib.autocomplete.AutoComplete.get_entity. This allows attackers to craft pickle payloads that bypass Picklescan's detection and execute arbitrary code when loaded. The vulnerability affects users relying on Picklescan to verify the safety of pickle files, particularly in contexts such as PyTorch models. Exploitation can lead to remote code execution and supply chain attacks through infected pickle files distributed in machine learning models or saved Python objects.
