CVE-2025-71357
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk16th percentile - higher than 16% of all known CVEs
Summary
A vulnerability in picklescan before version 0.0.30 allows bypassing detection of malicious pickle files. Attackers can use the idlelib.pyshell.ModifiedInterpreter.runcommand method in reduce functions to hide code that executes remote commands when the file is loaded by the victim.
Risk Assessment
The organization is at risk of remote code execution (RCE) by loading a crafted pickle file, which could lead to system compromise or data theft.
Recommendation
Immediately update picklescan to version 0.0.30 or later. Before updating, it is recommended to stop processing pickle files from untrusted sources.
Other vulnerabilities in picklescan przed wersją 0.0.30
See all- CVE-2025-71378High
The vulnerability in picklescan before version 0.0.30 fails to detect cProfile.runctx function calls in pickle file reduce methods, allowing attackers to bypass scanning and execute arbitrary code when a malicious pickle file is loaded via pickle.load().
- CVE-2025-71348High
The vulnerability in picklescan before version 0.0.28 fails to detect malicious pickle files that invoke the torch.utils._config_module.load_config function within reduce methods. Attackers can craft pickle files embedding arbitrary code that evades detection but executes during pickle.load, enabling remote code execution in supply chain attacks.
Original NVD description (English source)
picklescan before 0.0.30 fails to detect malicious pickle files using idlelib.pyshell.ModifiedInterpreter.runcommand in reduce methods. Attackers can embed undetected code in pickle files that executes remote commands when loaded by victims.
