Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Picklescan versions before 0.0.28 fail to flag pickle files that call torch.utils._config_module.load_config, so malicious files can pass its safety scan. An attacker who supplies a crafted pickle file can get it past the scan, and when a victim loads it with pickle.load(), arbitrary code runs. Upgrade picklescan to version 0.0.28 or later.
