- **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 behavior matches a web media viewer: it lazy-loads its UI, retrieves selected media for preview, and reports viewer performance events. The flagged network and filesystem indicators did not reveal unrelated collection or harmful actions.

## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified; the inspected network behavior supports media viewing and product performance analytics.

- **Trigger:** The viewer is rendered and loads media.

- **Impact:** Media content is retrieved for display and performance events are reported; no credential collection, unrelated host contact, or filesystem modification was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-02T02:03:27.151Z

### AI review details

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

- **Mechanism:** The entry lazy-loads the viewer; archive preview fetches its selected media source, and viewer lifecycle paths emit analytics events.

- **Rationale:** The inspected behavior matches a web media viewer: it lazy-loads its UI, retrieves selected media for preview, and reports viewer performance events. The flagged network and filesystem indicators did not reveal unrelated collection or harmful actions.

### Review decision

- **Verdict:** Clean

- **Confidence:** 89.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package describes a web media viewer, consistent with its purpose., The CommonJS entry re-exports a lazy-loaded viewer component., Archive preview fetches the selected source and reads its response as a blob., UFO experience metadata identifies the media-viewer component and reports package and media context.

- **Evidence against:** Viewer load and success paths automatically emit analytics and UFO experience events., The UFO metadata hardcodes packageVersion as 54.12.3 although this package is 54.12.4.

- **Public source:** [View source](<https://unpkg.com/@atlaskit/media-viewer@54.12.4/dist/cjs/viewers/archiveSidebar/archive-viewer-base.js>)

Archive preview fetches the selected source and reads its response as a blob.

Public source snippet (untrusted):

```javascript
return fetch(src);
                    case 1:
                      return _context3.abrupt("return", _context3.sent.blob());

```javascript
var startMediaFileUfoExperience = exports.startMediaFileUfoExperience = function startMediaFileUfoExperience() {
  getExperience().start();
};
var succeedMediaFileUfoExperience = exports.succeedMediaFileUfoExperience = function succeedMediaFileUfoExperience(properties) {
  getExperience().success({
    metadata: _objectSpread(_objectSpread({}, properties), {
