AI Security Review
scanned 14d ago · by lpm-firewall-aiThe manifest and source show a conditional document-processing dependency, but its implementation was not available for inspection. Under the review policy, this unresolved selected dependency prevents a clean verdict; the inspected parent source does not establish an attack.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Document processing with processor.name set to liteparse.
Impact
The dependency’s behavior on this feature path remains unverified; no malicious effect is confirmed.
Mechanism
The package imports LiteParse and calls its parse and screenshot methods; the dependency source was unavailable in the package snapshot.
AI rationale
The manifest and source show a conditional document-processing dependency, but its implementation was not available for inspection. Under the review policy, this unresolved selected dependency prevents a clean verdict; the inspected parent source does not establish an attack.
Evidence
package.jsonee/python/documents/processing/doc_processor.ts
Decision evidence
public snapshotAI called this Manual Review at 79.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The manifest declares @llamaindex/liteparse with the range ^1.0.1, and that dependency’s source was unavailable for inspection.
- The document processor imports LiteParse and calls it only when processor.name is liteparse.
- The postinstall hook runs scripts/postinstall.cjs; the inspected script removes node-liblzma, an optional dependency, with an explicit environment-variable opt-out.
Evidence against
- The LiteParse import and call are part of a named document-processing mode; the inspected parent source does not establish malicious behavior by that dependency.
- The postinstall script’s inspected removal is limited to node-liblzma and identifies its xz-only effect.
