CVE-2025-71356

CVE-2025-71356 affects picklescan prior to 0.0.28, which fails to detect malicious torch.fx.experimental.symbolic_shapes.ShapeEnv.evaluate_guards_expression calls embedded in pickle files. This enables arbitrary code execution when such pickle files are loaded by victims, as attackers can embed p...
