## Security analysis

### Published attack-surface review

- **Summary:** No malicious attack surface was identified. Archive preview code can retrieve the selected file for a custom renderer.

- **Trigger:** A caller supplies a custom renderer and invokes its binary-content helper while rendering an archive item.

- **Impact:** This supports the viewer's file-rendering function; no unrelated collection or transmission behavior was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-10T06:27:45.259Z

### AI review details

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

- **Mechanism:** The helper fetches that item's source URL and returns the response body as a blob.

- **Rationale:** The inspected manifest and archive viewer behavior are consistent with a media-viewing package. The network call is limited to a caller-invoked archive content helper, and the stylesheet finding is presentation CSS.

### 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 points to the viewer entrypoints and declares no lifecycle scripts; the package is an Atlassian media viewer., The required stylesheet contains ordinary presentation rules., The archive viewer fetches a source URL only when a supplied custom renderer calls its binary-content helper, then returns the response as a blob.
