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 exposes library entry points without an install hook, and the flagged stylesheet contains presentation rules. The archive fetch is part of rendering selected content and does not establish an attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-10T06:26:30.175Z - **Finished:** 2026-10-10T06:26:59.195Z - **Download time:** 762 ms - **Static scan time:** 1616 ms - **AI review time:** 26641 ms - **Total time:** 29020 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. The inspected archive network read is limited to retrieving the selected preview content for a custom renderer. - **Trigger:** A consumer displays an archive item and a configured custom renderer requests its binary content. - **Impact:** No independent exfiltration, persistence, destructive action, or unauthorized mutation is established by the inspected code. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:26:59.195Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The viewer fetches the selected content source and returns the response body as a blob. - **Rationale:** The manifest exposes library entry points without an install hook, and the flagged stylesheet contains presentation rules. The archive fetch is part of rendering selected content and does not establish an attack. ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package manifest identifies the published CommonJS and module entry points and contains no install lifecycle hook., The flagged stylesheet contains ordinary layout and typography declarations., Archive preview code renders recognized media types and offers custom renderers access to the selected content as a blob. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.8.34. - Review the evidence and your use of @atlaskit/media-viewer@54.8.34 before allowing it.
