Vulnerability Title
picklescan - Remote Code Execution via _operator.attrgetter Detection Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
picklescan before 0.0.34 fails to detect _operator.attrgetter function calls in pickle payloads, allowing attackers to bypass security checks. Remote attackers can craft malicious pickle files using _operator.attrgetter in reduce methods to execute arbitrary code when pickle.load() processes the file.
