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. Inspected source shows package-aligned archive viewing and ordinary CSS, with no install hook in the manifest. The network references are used to retrieve media content for rendering, not evidence of an attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-10T06:25:56.050Z - **Finished:** 2026-10-10T06:26:24.040Z - **Download time:** 1031 ms - **Static scan time:** 1541 ms - **AI review time:** 25418 ms - **Total time:** 27990 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. Network activity in the inspected archive viewer supports displaying selected media content. - **Trigger:** The application invokes the archive viewer for a media file, or a custom renderer requests an archive entry's binary content. - **Impact:** The inspected behavior retrieves content for rendering; no malicious behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:26:24.040Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The viewer obtains a file URL from the media client, reads ZIP contents, and fetches the selected entry for a custom renderer. - **Rationale:** Inspected source shows package-aligned archive viewing and ordinary CSS, with no install hook in the manifest. The network references are used to retrieve media content for rendering, not evidence of an attack. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest identifies a browser media viewer package and has no install lifecycle hook., The required CSS contains styling rules only., Archive loading retrieves a media file URL and reads it as a ZIP archive., A custom archive renderer fetches the selected entry when its content callback is invoked. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.8.7. - Review the evidence and your use of @atlaskit/media-viewer@54.8.7 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.
