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 source supports ordinary archive viewing behavior, and the required CSS path contains styling rules. No concrete attack surface was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T06:26:08.401Z - **Finished:** 2026-10-10T06:26:35.225Z - **Download time:** 754 ms - **Static scan time:** 1769 ms - **AI review time:** 24301 ms - **Total time:** 26824 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-related behavior reads archive content supplied to the viewer and serves it to its custom renderer. - **Trigger:** A consumer renders an archive entry, optionally through a configured custom renderer. - **Impact:** No package-controlled network destination, credential transfer, or install-time action was established by the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:26:35.225Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The code reads the selected entry as a blob, creates a browser object URL, and fetches that URL to provide the blob to the custom renderer. - **Rationale:** The inspected source supports ordinary archive viewing behavior, and the required CSS path contains styling rules. No concrete attack surface was established. ### 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 a browser media-viewer package and its CJS entry point., Archive entries are read as blobs and exposed through browser object URLs for viewing., The archive custom-renderer helper fetches the generated local source URL and returns its blob., The required CSS finding path contains ordinary visual styling rules. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.8.26. - Review the evidence and your use of @atlaskit/media-viewer@54.8.26 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.
