This link is maintained to preserve external references.\n\n### Original Description\npicklescan 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.\n\n## Affected packages\n\n- `picklescan < 1.0.4`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `picklescan 1.0.4`","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
