The flagged archive fetch supports a selected media source for a custom renderer, while the required flagged CSS is styling. - **Trigger:** A custom renderer requests binary content for an archive item. - **Impact:** This provides media content to viewer functionality; the inspected evidence does not show credential collection, unrelated exfiltration, or install-time behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:27:07.991Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The archive viewer fetches the item's source and returns its blob to the renderer. - **Rationale:** Inspected source supports ordinary media-viewer behavior, and the flagged CSS contains styles. No concrete malicious behavior was established. ### Review decision - **Verdict:** Clean - **Confidence:** 89.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest identifies a browser media viewer and names bundled JavaScript entrypoints., The flagged CSS excerpt contains presentation styles only., The archive viewer exposes a function that fetches the selected source when binary content is requested by a custom renderer. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.8.28. - Review the evidence and your use of @atlaskit/media-viewer@54.8.28 before allowing it.
