Astra Linux – Vulnerability in Python 3.7

There is a flaw in Python 3’s pydoc documentation. A local or nearby attacker who discovers or can convince another local or nearby user to start a pydoc server could access the server and use it to disclose sensitive information belonging to that user that they would not normally be able to...

Fickling vulnerable to use of ctypes and pydoc gadget chain to bypass detection

Fickling's assessmentpydoc and ctypes were added to the list of unsafe imports https://github.com/trailofbits/fickling/commit/b793563e60a5e039c5837b09d7f4f6b92e6040d1. Original report SummaryBoth ctypes and pydoc modules arent explictly blocked. Even other existing pickle scanning tools like...

Picklescan has Incomplete List of Disallowed Inputs

SummaryCurrently picklescanner only blocks some specific functions of the pydoc and operator modules. Attackers can use other functions within these allowed modules to go through undetected and achieve RCE on the final user. Particularly pydoc.locate: Can dynamically resolve and import arbitrary...

GHSA-6V84-V468-3C7F Duplicate Advisory: Picklescan has Incomplete List of Disallowed Inputs

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-84r2-jw7c-4r5q. This link is maintained to preserve external references. Original Description picklescan before 0.0.33 contains an incomplete deny-list that fails to block pydoc.locate and operator.methodcaller...

CVE-2025-71320

picklescan before 0.0.33 contains an incomplete deny-list that fails to block pydoc.locate and operator.methodcaller functions, allowing attackers to bypass security checks. Remote attackers can craft malicious pickle files using these unblocked functions to achieve arbitrary code execution when...

CVE-2025-71320

The CVE identifies a vulnerability in picklescan prior to 0.0.33, where an incomplete deny-list fails to block pydoc.locate and operator.methodcaller. This allows remote attackers to craft malicious pickle files that, when deserialized, yield arbitrary code execution. The issue is tied to deseria...

Remote Code Execution (RCE)

fickling is vulnerable to Remote Code Execution RCE. The vulnerability is due to the failure to explicitly block dangerous modules such as ctypes and pydoc, which allows an attacker to chain pydoc.locate with ctypes during pickle analysis to achieve RCE while the malicious pickle file is still...
