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...

CVE-2025-71320 picklescan - Remote Code Execution via Incomplete Disallowed Inputs

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...

Picklescan has Incomplete List of Disallowed Inputs

Summary Currently 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...
