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.collect_env.run, a PyTorch function, so a malicious pickle can pass the scan. An attacker who supplies such a file can get remote code execution when a victim unpickles it after the scan reports it as safe. Upgrade picklescan to version 0.0.28 or later.
