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 manifest and inspected archive viewer code show ordinary viewer functionality, with the flagged fetch operating on a locally created archive-entry URL. The flagged CSS contains presentation rules, and no malicious behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-10T06:26:11.036Z - **Finished:** 2026-10-10T06:26:40.406Z - **Download time:** 1011 ms - **Static scan time:** 1895 ms - **AI review time:** 26464 ms - **Total time:** 29370 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 surface was identified in the inspected package entry points or archive viewer behavior. The flagged network call reads selected archive content through a local viewer URL. - **Trigger:** A consumer imports and uses the viewer, then selects an archive entry or renders it through a custom renderer. - **Impact:** No external data transfer, credential access, persistence, or destructive action was identified in the inspected behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:26:40.406Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The viewer creates a local object URL from the selected archive entry; custom rendering fetches that URL to return the entry blob. - **Rationale:** The manifest and inspected archive viewer code show ordinary viewer functionality, with the flagged fetch operating on a locally created archive-entry URL. The flagged CSS contains presentation rules, and no malicious behavior was identified. ### 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 points to bundled CommonJS and ESM viewer entry points and shows ordinary Atlaskit runtime dependencies., Archive entry content is read from the selected entry as a blob and exposed through a local object URL., The custom archive renderer fetches the generated source URL and returns its blob; this is local viewer content handling., The flagged CSS file contains ordinary presentation rules for the viewer. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.8.27. - Review the evidence and your use of @atlaskit/media-viewer@54.8.27 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.
