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 package metadata, the required CSS finding, and the flagged archive viewer source. The observed code supports user-facing archive preview behavior and shows no concrete malicious action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-10T06:27:39.510Z - **Finished:** 2026-10-10T06:28:20.324Z - **Download time:** 1020 ms - **Static scan time:** 1441 ms - **AI review time:** 38352 ms - **Total time:** 40814 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 in the inspected package entry metadata, CSS, or flagged archive viewer. Archive preview and optional custom rendering are ordinary viewer behavior. - **Trigger:** Application imports and uses the viewer, then displays an archive entry; custom rendering requires a matching configured renderer. - **Impact:** No confirmed attack surface was established; observed network use is limited to retrieving archive content for rendering. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:28:20.324Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The archive viewer selects renderers based on archive file data and viewer options and fetches the entry source for a selected custom renderer. - **Rationale:** Inspected package metadata, the required CSS finding, and the flagged archive viewer source. The observed code supports user-facing archive preview behavior and shows no concrete malicious action. ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json identifies the requested Atlaskit media viewer package and version., The required CSS finding contains ordinary component styling declarations., The flagged archive viewer renders a custom renderer only when one is selected from viewer options., Archive entries are routed by media type into code or other viewer components. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.9.9. - Review the evidence and your use of @atlaskit/media-viewer@54.9.9 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.
