Is fastembed safe?
- Node.js filesystem read
- Node.js filesystem write/delete
- Node.js network egress
fastembed is an AI npm_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 network egress — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).
fastembed 3.0.0
Automated static-analysis result. It can contain false positives and false negatives, and is not a claim about the intent of fastembed'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 reads files from disk.
const config = JSON.parse(fs.readFileSync(configPath, "utf-8"));
const tokenizerConfig = JSON.parse(fs.readFileSync(tokenizerFilePath, "utf-8"));
const tokensMap = JSON.parse(fs.readFileSync(tokensMapPath, "utf-8"));
const config = JSON.parse(fs.readFileSync(configPath, "utf-8"));
const tokenizerConfig = JSON.parse(fs.readFileSync(tokenizerFilePath, "utf-8"));
const tokensMap = JSON.parse(fs.readFileSync(tokensMapPath, "utf-8"));
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.
}), fs.createWriteStream(partialFilePath));
fs.rmSync(partialFilePath, { force: true });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.
The component makes outbound network requests.
const response = await fetch(url);
const response = await fetch(url);
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.
