CVE-2025-71358: picklescan - Remote Code Execution via idlelib.autocomplete.AutoComplete.get_entity

picklescan before 0.0.29 fails to detect malicious pickle files that exploit idlelib.autocomplete.AutoComplete.get_entity function in reduce methods. Attackers can embed undetected code in pickle files that executes arbitrary commands when loaded by victims using pickle.load().

Security readout for executives and security teams

Plain-English summary

CVE-2025-71358 affects picklescan, a tool used to inspect Python pickle files. Versions before 0.0.29 may miss malicious pickle content that can run arbitrary commands when a victim later loads the file. The main business risk is misplaced trust in a scan result for untrusted pickle or model artifacts.

Executive priority

Prioritize remediation if the organization handles external pickle, ML model, or Python artifact files. The issue is high severity because it weakens a safety control and can lead to command execution after a user loads a malicious file.

Technical view

picklescan fails to detect pickle reduce-method abuse involving idlelib.autocomplete.AutoComplete.get_entity. The vulnerability maps to CWE-502 and can allow arbitrary command execution during pickle.load() after user interaction. The reported CVSS is 8.1, network attack vector, low complexity, no privileges, and required user interaction.

Likely exposure

Exposure is likely where teams accept, download, scan, or exchange pickle-based artifacts and then load them in Python workflows. The source bundle only names picklescan as affected; it does not establish exposure for other products or platforms.

Exploitation context

The advisory describes malicious pickle files that evade picklescan detection and execute when loaded by a victim. KEV is false in the bundle, and no cited source here confirms active exploitation in the wild.

Researcher notes

Evidence is limited to the supplied CVE, GitHub advisory reference, and VulnCheck reference. The vulnerable behavior is detection bypass for a pickle deserialization gadget path, not a direct remote service exploit. User interaction is required because execution occurs when the victim loads the pickle.

Mitigation direction

  • Identify all environments using picklescan.
  • Move off picklescan versions before 0.0.29 where applicable.
  • Check the GitHub advisory for confirmed fixed-version guidance.
  • Avoid loading pickle files from untrusted sources.
  • Treat prior clean picklescan results as insufficient for untrusted artifacts.

Validation and detection

  • Inventory dependency manifests and build images for picklescan usage.
  • Confirm the deployed picklescan version in CI and analyst workstations.
  • Review workflows that load pickle files after scanning.
  • Reassess recently accepted pickle artifacts from untrusted sources.
  • Check vendor advisory updates for detection or remediation changes.
