CVE-2026-31222 is a high-severity flaw (CVSS 8.8) affecting snorkel. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The snorkel library thru v0.10.0 contains an insecure deserialization vulnerability (CWE-502) in the Trainer.load() method of the Trainer class. The method loads model checkpoint 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
