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 shows ordinary built entrypoints and no install lifecycle command, while the flagged CSS is styling data. The flagged fetch is used to provide selected archive content to a custom renderer; no malicious behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T06:27:33.305Z - **Finished:** 2026-10-10T06:28:20.608Z - **Download time:** 1518 ms - **Static scan time:** 1648 ms - **AI review time:** 44136 ms - **Total time:** 47303 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 observed network request supports the archive viewer's custom rendering of a selected archive entry. - **Trigger:** A custom renderer is selected for an archive entry and requests its binary content. - **Impact:** No confirmed attack surface was established; the request is tied to rendering selected media content. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:28:20.608Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The viewer fetches the entry source and returns its response body as a blob. - **Rationale:** The manifest shows ordinary built entrypoints and no install lifecycle command, while the flagged CSS is styling data. The flagged fetch is used to provide selected archive content to a custom renderer; no malicious behavior was identified. ### 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 exposes built JavaScript entrypoints and declares no install lifecycle command., The flagged CSS file contains ordinary style rules., The archive viewer fetches the selected entry source only when a custom renderer requests its binary content. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.10.0. - Review the evidence and your use of @atlaskit/media-viewer@54.10.0 before allowing it.
