Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
vLLM 0.10.2-0.11.0 deserialized user-supplied PyTorch tensors via torch.load() in the Completions API. Memory corruption, potential RCE.
A critical PyTorch RCE bypassed the safety property of torch.load(weights_only=True). We analyze the bug and explain why safetensors should now be the default.
