CVE-2025-71369 | picklescan before 0.0.28 fails to detect malicious pickle fi… | CVSS 8.1 HIGH

Description

picklescan before 0.0.28 fails to detect malicious pickle files that use torch.utils.data.datapipes.utils.decoder.basichandlers in reduce methods, allowing attackers to bypass safety checks. Remote attackers can embed undetected malicious code in pickle files that executes during deserialization, enabling remote code execution.
