CVE-2025-71347 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. picklescan before 0.0.33 fails to detect malicious pickle files using numpy.f2py.crackfortran.param_eval function in reduce methods, allowing attackers to bypass security checks. Remote attackers can embed undetected code in pickle files that executes during deserialization, enabling arbitrary code execution in applications loading untrusted pickle data.. EPSS estimates a 0.45% chance of exploitation in the next 30 days.
