Assigner: VulnCheck
Reserved: 20.06.2026 Published: 04.07.2026 Updated: 04.07.2026

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.
