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...

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...

CVE-2026-22608

Fickling is a Python pickling decompiler and static analyzer. Prior to version 0.1.7, both ctypes and pydoc modules aren't explicitly blocked. Even other existing pickle scanning tools like picklescan do not block pydoc.locate. Chaining these two together can achieve RCE while the scanner still...
