- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 54.8.33
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The inspected manifest points to normal library entrypoints, and the flagged code handles archive data for preview. The network-related fetch uses the viewer's preview source; no malicious network behavior is established by the inspected evidence.

## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The flagged archive code previews selected archive content, and the CSS file contains viewer styling.

- **Trigger:** A caller displays an archive and selects an entry, or invokes its custom renderer content callback.

- **Impact:** These inspected behaviors support archive preview and do not establish credential access, exfiltration, or other malicious effects.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T06:27:05.091Z

### AI review details

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

- **Mechanism:** The viewer obtains a selected entry's blob, creates a local object URL, and lets the custom renderer fetch that source as a blob.

- **Rationale:** The inspected manifest points to normal library entrypoints, and the flagged code handles archive data for preview. The network-related fetch uses the viewer's preview source; no malicious network behavior is established by the inspected evidence.

### Review decision

- **Verdict:** Clean

- **Confidence:** 91.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest identifies the package and release, and points to library entrypoints., Archive entries are read as blobs and turned into local object URLs for preview., The custom renderer fetches the preview source and returns its blob; this is part of archive viewing., The required CSS file contains ordinary viewer styling.
