Lifecycle Timeline
2DescriptionCVE.org
picklescan before 0.0.33 fails to detect operator.methodcaller function calls in pickle files, allowing attackers to bypass security checks. Remote attackers can craft malicious pickle payloads using operator.methodcaller that execute arbitrary code when loaded, compromising systems relying on picklescan for validation.
AnalysisAI
Detection bypass in picklescan before 0.0.33 lets attackers slip malicious pickle files past its security scanner by using operator.methodcaller, a callable the scanner's blocklist did not recognize. Any ML pipeline, model hub, or workflow that trusts picklescan to vet untrusted pickle/model files is affected, because a crafted payload will be marked safe yet execute arbitrary code the moment the file is deserialized. No public exploit identified at time of analysis and the flaw is not in CISA KEV, but the bypass technique is straightforward and the issue is tagged RCE by the reporting source (VulnCheck).
