## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 22 low-signal pattern(s) reviewed.

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 5.6.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

The inspected credential path uses an environment-configured remote LiteLLM URL, and the flagged host appears only as an example in generated instructions. The selected @llamaindex/liteparse runtime dependency could not be inspected, so its behavior remains unresolved.

## Latest scan

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No concrete attack was identified in the inspected package source. Review remains unresolved because an installed runtime dependency used for document processing could not be inspected.

- **Trigger:** Document processing that selects the LiteParse parser.

- **Impact:** The dependency’s behavior cannot be assessed from the available source; no attack behavior was confirmed.

- **Evidence paths:** package.json, ee/python/documents/processing/doc\_processor.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T19:47:55.052Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The package imports and instantiates LiteParse from @llamaindex/liteparse, whose source was unavailable in this review.

- **Rationale:** The inspected credential path uses an environment-configured remote LiteLLM URL, and the flagged host appears only as an example in generated instructions. The selected @llamaindex/liteparse runtime dependency could not be inspected, so its behavior remains unresolved.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 75.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The manifest runs a postinstall script during installation; that script sets up the package’s Python environment and removes a located node-liblzma directory., The manifest declares @llamaindex/liteparse, which document processing imports and instantiates; its selected package source was unavailable for inspection., Remote LiteLLM requests use the configured LITELLM\_BASE\_URL and require EXULU\_API\_KEY when remote client mode is enabled., The ai.open.de reference appears in generated setup instructions as an example of the user’s instance URL.

- **Evidence against:** The inspected source does not establish a fixed publisher-selected recipient for the flagged credential transfer.

## Affected versions and remediation

- Review the evidence and your use of @exulu/backend@5.6.0 before allowing it. Restrict the permissions described in this report.
