Findings
Scanned 2026-08-25 · published from a community scan.
medium Pickle-serialized weights, no safetensors
Weights ship only as pickle-based files (RWKV-4-Pile-1B5-20220814-4526.pth, RWKV-4-Pile-1B5-20220822-5809.pth, RWKV-4-Pile-1B5-20220903-8040.pth, …). Loading pickle executes arbitrary code from the file — prefer a safetensors release or load in a sandbox.
How to fix
Convert the weights to safetensors before loading them anywhere that matters.
- Do not load the pickle files in-process — pickle deserialization executes arbitrary code from the file.
- Convert locally in a sandbox: `pip install safetensors` and use `safetensors.torch.save_file` on a state dict loaded with `torch.load(..., weights_only=True)` (refuses most code-execution payloads), or use Hugging Face's `convert.py` space/script.
- Pin the exact revision hash you converted from, and load only your converted safetensors artifact from then on.
info Pickle static analysis clean
Opcode-level parse of RWKV-4-Pile-1B5-20220814-4526.pth, RWKV-4-Pile-1B5-20220822-5809.pth, RWKV-4-Pile-1B5-20220903-8040.pth, RWKV-4-Pile-1B5-20220929-ctx4096.pth (no code executed) found only standard serialization globals (3 distinct, all torch/collections/numpy). Pickle remains an executable format — this verifies the current bytes, not future uploads; prefer a safetensors release.
Remediation guidance addresses the documented findings only. It is evidence-driven repair, not a safety certification of the model.
