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 manifest presents compiled viewer entry points and the required CSS contains visual styling. The flagged fetch is tied to custom archive rendering and supplies the selected file content; the inspected sources show no concrete attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T06:27:01.713Z - **Finished:** 2026-10-10T06:27:28.658Z - **Download time:** 1024 ms - **Static scan time:** 1476 ms - **AI review time:** 24444 ms - **Total time:** 26945 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 inspected network request retrieves archive content for a custom renderer. - **Trigger:** A consumer renders an archive entry through a configured custom renderer and requests its binary content. - **Impact:** The request supports ordinary archive preview behavior; no malicious effect was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:27:28.658Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The viewer fetches the selected source and returns the response body as a blob. - **Rationale:** The inspected manifest presents compiled viewer entry points and the required CSS contains visual styling. The flagged fetch is tied to custom archive rendering and supplies the selected file content; the inspected sources show no concrete attack behavior. ### 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 identifies the package and exposes compiled viewer entry points; it shows no lifecycle scripts in the inspected manifest sections., The required CSS file contains ordinary visual styling declarations., Archive viewer code fetches the selected source to provide binary content to a custom renderer; no unrelated destination or credential forwarding is shown. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.6.1. - Review the evidence and your use of @atlaskit/media-viewer@54.6.1 before allowing it.
