Is langchain safe?
- Node.js filesystem read
- Node.js filesystem write/delete
langchain 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: filesystem read and filesystem write — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).
langchain 1.5.14
Automated static-analysis result. It can contain false positives and false negatives, and is not a claim about the intent of langchain'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)
The component reads files from disk.
const fileContent = await fs.readFile(this.getFullPath(key));
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.
await fs.unlink(this.getFullPath(key));
await Promise.all(entries.filter((file) => file.endsWith(".tmp")).map((tempFile) => fs.unlink(path.join(rootPath, tempFile)).catch(() => {})));await fs.writeFile(tempPath, content);
await fs.writeFile(fullPath, content);
await fs.unlink(tempPath).catch(() => {});await fs.unlink(tempPath).catch(() => {});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.
