Is hyparquet safe?
- Node.js network egress
- npm prepare hook
hyparquet is an AI npm_package analyzed by SkillTotal's deterministic static scanner. The scan found no malicious indicators, though 2 risky constructs are reported for review. It can: install time execution and network egress — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).
hyparquet 1.31.2
Automated static-analysis result. It can contain false positives and false negatives, and is not a claim about the intent of hyparquet'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 (2)
package.json has a 'prepare' script (runs on git/local installs and before publishing).
"prepare": "npm run build:types",
Why it matters: Usually a build step, but confirm it doesn't fetch or run remote code.
Fix: Usually a legitimate build step; confirm it only builds and does not fetch or execute remote code.
The component makes outbound network requests.
const res = await fetch(url, { ...requestInit, method: 'HEAD' })const res = await fetch(url, { ...init, headers })Why it matters: Usually legitimate, but confirm the destinations are expected and no sensitive data leaves.
Fix: Confirm the destination hosts are expected and that no sensitive data is sent off-host.
