CVE-2025-71374 | picklescan before 0.0.29 fails to detect the built-in python… | CVSS 8.1 HIGH

Description

picklescan before 0.0.29 fails to detect the built-in python profile.Profile.run function when used in pickle reduce methods, allowing attackers to execute arbitrary code. Remote attackers can craft malicious pickle files that bypass picklescan detection and achieve code execution upon deserialization.
