The method loads model weight files using torch.load() without enabling the security-restrictive weights_only=True parameter. This default behavior allows the deserialization of arbitrary Python objects via the Pickle module. A remote attacker can exploit this by providing a maliciously crafted model file, leading to arbitrary code execution on the victim's system when the file is loaded via the vulnerable method."}], "lastModified": "2026-05-13T15:44:54.743", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:snorkel:snorkel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F2E7FC3A-64C0-4F69-84DD-FC9BA0883D08", "versionEndIncluding": "0.10.0"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
