CVE-2026-56315
CriticalCVSS 9.8Summary
Picklescan before 1.0.4 fails to block at least seven Python standard library modules, allowing for remote code execution. Attackers can craft malicious pickle files importing these unblocked modules, bypassing picklescan's safety validation.
Risk Assessment
Organizations are exposed to remote code execution, which can lead to serious security breaches and data loss. Exploiting this vulnerability may allow attackers full control over the system.
Recommendation
It is recommended to update picklescan to version 1.0.4 or later to block access to dangerous modules. Additionally, an audit of existing pickle files should be conducted to identify potential threats.
Original NVD description (English source)
picklescan before 1.0.4 fails to block at least seven Python standard library modules (including uuid, _osx_support, _aix_support, _pyrepl.pager, and imaplib) exposing eight functions that provide direct arbitrary command execution. Attackers can craft malicious pickle files importing these unblocked modules to achieve remote code execution while bypassing picklescan's safety validation entirely.
