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...

Remote Code Execution (RCE)

picklescan is vulnerable to Remote Code Execution RCE. The vulnerability is due to improper handling of untrusted pickle data in the function’s reduce flow, which allows an attacker to craft a malicious pickle that bypasses the victim’s Picklescan check and achieve arbitrary code execution when t...

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...

Protection Mechanism Failure

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 Vulnerable to Unsafe Globals Check Bypass through Subclass Imports

Summary The vulnerability allows malicious actors to bypass PickleScan's unsafe globals check, leading to potential arbitrary code execution. The issue stems from PickleScan's strict check for full module names against its list of unsafe globals. By using subclasses of dangerous imports instead o...

PT-2025-38143

Name of the Vulnerable Software and Affected Versions mmaitre314 picklescan versions up to and including 0.0.30 Description A Protection Mechanism Failure in picklescan allows a remote attacker to bypass the unsafe globals check. This occurs because the scanner uses an exact match for module name...

Improper Input Validation

picklescan are vulnerable to improper input validation. The vulnerability is due to a parsing logic error in handling the STACKGLOBAL opcode, where the function listglobals tracks arguments in the wrong range, which allows an attacker to bypass proper opcode processing...
