## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified. The inspected network and analytics behavior fits media rendering and experience tracking.

- **Trigger:** The viewer chunk loads when the exported component is rendered; archive content is fetched when needed for viewing.

- **Impact:** No malicious impact was identified in the inspected source.

- **Review source:** ai\_review

- **Reviewed:** 2026-11-03T18:13:33.785Z

### AI review details

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

- **Mechanism:** The package lazily loads its viewer code, reports media-viewer experience metadata, and fetches selected archive media as a blob.

- **Rationale:** The inspected entry point loads the viewer lazily, and the observed fetch is used to render selected archive media. The analytics code describes media-viewer experiences and package metadata; no malicious behavior was found.

### Review decision

- **Verdict:** Clean

- **Confidence:** 92.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package manifest identifies this as Atlassian’s media viewer and points its CommonJS entry to the built viewer., The entry point exports the viewer loader; the loader fetches the viewer chunk lazily when the component is rendered., UFO analytics records the package name, version, viewer component, and feature flags for media-viewer experiences., Archive viewing fetches the selected media source and reads its response as a blob, consistent with the package’s purpose.

- **Public source:** [View source](<https://unpkg.com/@atlaskit/media-viewer@54.12.8/dist/cjs/components/media-viewer-loader.js>)

The entry point exports the viewer loader; the loader fetches the viewer chunk lazily when the component is rendered.

Public source snippet (untrusted):

```javascript
var MediaViewer = /*#__PURE__*/(0, _react.lazy)(function () {
  return (0, _chunkLoaders.loadMediaViewerChunk)().then(function (_ref) {
    var MediaViewerWithErrorBoundary = _ref.MediaViewerWithErrorBoundary;

- **Confidence:** 92.0%
- **Path:** dist/cjs/analytics/ufoExperiences.js
- **Public source:** [View source](<https://unpkg.com/@atlaskit/media-viewer@54.12.8/dist/cjs/analytics/ufoExperiences.js>)

UFO analytics records the package name, version, viewer component, and feature flags for media-viewer experiences.

Public source snippet (untrusted):

```javascript
var packageName = "@atlaskit/media-viewer";
var packageVersion = "54.12.7";
var ufoExperience;
var getExperience = function getExperience() {
  if (!ufoExperience) {
    var inlineExperience = {
      platform: {
        component: 'media-viewer'
      },
      type: _experienceTypes.ExperienceTypes.Experience,
      performanceType: _experienceTypes.ExperiencePerformanceTypes.InlineResult,
      featureFlags: (0, _mediaCommon.getFeatureFlagKeysAllProducts)()
    };
    ufoExperience = new _experience.UFOExperience('media-file', inlineExperience);
  }
  return ufo

- **Public source:** [View source](<https://unpkg.com/@atlaskit/media-viewer@54.12.8/dist/cjs/viewers/archiveSidebar/archive-viewer-base.js>)

Archive viewing fetches the selected media source and reads its response as a blob, consistent with the package’s purpose.

Public source snippet (untrusted):

```javascript
fetch(src);
                    case 1:
                      return _context3.abrupt("return", _context3.sent.blob());
                    case 2:
