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. Source inspection found no lifecycle hook or self-dependency in the manifest. The archive viewer's fetch is tied to the selected file and custom renderer, and the required CSS path contains styling rules; the scanner's CSS parsing limitation does not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-10T06:28:10.292Z - **Finished:** 2026-10-10T06:28:49.184Z - **Download time:** 1292 ms - **Static scan time:** 1679 ms - **AI review time:** 35921 ms - **Total time:** 38892 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified. The reviewed network call supports the archive viewer's custom-renderer file display flow. - **Trigger:** A consumer displays an archive item through a custom renderer and requests its binary content. - **Impact:** No unrelated network destination, credential forwarding, or package-side install behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:28:49.184Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The viewer fetches the selected item source and returns the response blob to the renderer. - **Rationale:** Source inspection found no lifecycle hook or self-dependency in the manifest. The archive viewer's fetch is tied to the selected file and custom renderer, and the required CSS path contains styling rules; the scanner's CSS parsing limitation does not establish malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest identifies the package and published entry points; no lifecycle hooks or self-dependency are present., The required CSS file contains styling rules., The archive viewer fetches the selected source only to provide a custom renderer with that file's binary content; no unrelated destination or exfiltration behavior is shown. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.11.7. - Review the evidence and your use of @atlaskit/media-viewer@54.11.7 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
