Do you check auto_map before loading a model? Picking a model can execute code
iamjessew · reddit · 2026-10-06
A Reddit ML thread highlights an overlooked attack surface: automap in a repo's config. combined with trustremotecode can lead to arbitrary code execution. The trigger: an Unsloth Studio post showed that merely selecting a model in the UI — no weights loaded, no inference — ran Python from the repo, because a capability check called AutoConfig with trustremotecode on (fixed in 2026.6.9).
Key points:
- The transformers path executes repo-shipped code; GGUF via llama.cpp mostly avoids the Python layer
- The poster asks for best practices: pin commit hashes, grep for automap/.py files, sandbox new repos, or rely on download counts?
If you pull models locally, this is an attack surface worth auditing.
