Is safetensors safe?
- Python shell/command execution
- Python filesystem read
- Python filesystem write/delete
safetensors is an AI python_package analyzed by SkillTotal's deterministic static scanner. The scan found no malicious indicators, though 3 risky constructs are reported for review. It can: filesystem read, filesystem write and shell execution — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).
safetensors 0.8.0
Automated static-analysis result. It can contain false positives and false negatives, and is not a claim about the intent of safetensors's authors. Report a false positive.
Behavioral traits
How this component maps to the CSA agentic threat model. Descriptive — it never affects the risk score.
Findings (3)
The component can run operating-system commands or spawn processes.
_ = subprocess.check_output(["ruff", "format", f.name])
Why it matters: Powerful and often legitimate — confirm the commands aren't built from untrusted input.
Fix: Confirm the command and its arguments are fully controlled and not derived from untrusted input; avoid shell=True.
The component reads files from disk.
with open(config_filename, "r") as f:
with open(filename, "r") as f:
with open(filename, "r") as f:
with open(filename, "r") as f:
with open(filename, "r") as f:
Why it matters: Usually legitimate, but worth confirming it can't be steered into reading sensitive files.
Fix: Confirm which files are read and that paths cannot be influenced by untrusted input to reach sensitive locations.
The component writes or deletes files on disk.
with open(index, "w") as f:
shutil.rmtree(folder)
with open(filename, "w") as f:
Why it matters: Usually legitimate, but worth confirming the paths can't be controlled by untrusted input.
Fix: Confirm which files are written/deleted and that paths cannot be influenced by untrusted input.
