Picklescan Bugs Allow Malicious PyTorch Models to Evade Scans and Execute Code

Three critical security flaws have been disclosed in an open-source utility called Picklescan that could allow malicious actors to execute arbitrary code by loading untrusted PyTorch models, effectively bypassing the tool's protections. Picklescan, developed and maintained by Matthieu Maitre...

Improper Input Validation

picklescan is vulnerable to Improper Input Validation. The vulnerability is due to inadequate validation in the scanning logic that fails to properly inspect pickle files with PyTorch-related extensions, which allows an attacker to bypass security checks and execute malicious code when the file i...

Remote Code Execution (RCE)

picklescan is vulnerable to Remote Code Execution RCE. The vulnerability is due to the idlelib.run.Executive.runcode function executing arbitrary pickle files, which allows an attacker to run malicious code remotely...

Remote Code Execution (RCE)

cProfile is vulnerable to Remote Code Execution RCE.The vulnerability is due to unsafe deserialization/execution because cProfile.runctx can be abused to execute code from untrusted pickle files passed into its execution context...

Deserialization Of Untrusted Data

picklescan is vulnerable to Deserialization Of Untrusted Data. The vulnerability is due to the function fetching and unpickling remote pickle files without validation, which allows an attacker to supply a crafted pickle that executes arbitrary code when deserialized...

Duplicate Advisory: Picklescan: ZIP archive scan bypass is possible through non-exhaustive Cyclic Redundancy Check

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-m4j5-5x4r-2xp9. This link is maintained to preserve external references. Original Description An Improper Handling of Exceptional Conditions vulnerability in the ZIP archive scanning component of mmaitre314...

CVE-2025-10156 PickleScan Security Bypass via Bad CRC in ZIP Archive

An Improper Handling of Exceptional Conditions vulnerability in the ZIP archive scanning component of mmaitre314 picklescan allows a remote attacker to bypass security scans. This is achieved by crafting a ZIP archive containing a file with a bad Cyclic Redundancy Check CRC, which causes the...

Remote Code Execution (RCE)

picklescan is vulnerable to Remote Code Execution RCE. The vulnerability is due to unsafe deserialization because torch.utils.configmodule.loadconfig used in reduce can load malicious pickle files that bypass Picklescan checks and execute arbitrary code during pickle.load...

Insecure Deserialization

picklescan is vulnerable to Insecure Deserialization. The vulnerability is due to the use of torch.utils.collectenv.run function to execute remote pickle files, which allows an attacker to execute arbitrary code...

Protection Mechanism Failure

Overview picklescan is a Security scanner detecting Python Pickle files performing suspicious actions Affected versions of this package are vulnerable to Protection Mechanism Failure via the scanbytes function. An attacker can bypass detection of malicious content by disguising a standard pickle...

Picklescan Bypass is Possible via File Extension Mismatch

Summary Picklescan can be bypassed, allowing the detection of malicious pickle files to fail, when a standard pickle file is given a PyTorch-related file extension e.g., .bin. This occurs because the scanner prioritizes PyTorch file extension checks and errors out when parsing a standard pickle...

Picklescan: ZIP archive scan bypass is possible through non-exhaustive Cyclic Redundancy Check

Summary Picklescan's ability to scan ZIP archives for malicious pickle files is compromised when the archive contains a file with a bad Cyclic Redundancy Check CRC. Instead of attempting to scan the files within the archive, whatever the CRC is, Picklescan fails in error and returns no results...

Picklescan is missing detection when calling built-in python cProfile.run

Summary Using cProfile.run function, which is a built-in python library function to execute remote pickle file. Details The attack payload executes in the following steps: First, the attacker craft the payload by calling to cProfile.run function in reduce method Then when the victim after checkin...

GHSA-9W88-8RMG-7G2P Picklescan is missing detection when calling built-in python cProfile.runctx

Summary Using cProfile.runctx function, which is a built-in python library function to execute remote pickle file. Details The attack payload executes in the following steps: First, the attacker craft the payload by calling to cProfile.runctx function in reduce method Then when the victim after...

GHSA-CJ3C-V495-4XQH Picklescan has a missing detection when calling built-in python code.InteractiveInterpreter

Summary Using code.InteractiveInterpreter.runcode, which is a built-in python library function to execute remote pickle file. Details The attack payload executes in the following steps: First, the attacker craft the payload by calling to code.InteractiveInterpreter.runcode function in reduce meth...

Picklescan has a missing detection when calling built-in python idlelib.autocomplete.AutoComplete.get_entity

Summary Using idlelib.autocomplete.AutoComplete.getentity, which is a built-in python library function to execute remote pickle file. Details The attack payload executes in the following steps: First, the attacker craft the payload by calling to idlelib.autocomplete.AutoComplete.getentity functio...
