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 manifest and entrypoint show no install-time execution, and the flagged fetch operates on a blob URL created from the selected archive item. The required stylesheet contains ordinary styling rules; no malicious behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-14T21:55:30.663Z - **Finished:** 2026-10-14T21:56:06.765Z - **Download time:** 1290 ms - **Static scan time:** 1736 ms - **AI review time:** 33076 ms - **Total time:** 36102 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 flagged fetch reads a locally created blob URL for an archive entry. - **Trigger:** A viewer consumer selects an archive entry and a custom renderer requests its binary content. - **Impact:** The inspected behavior does not establish outbound data transfer, credential access, or system mutation. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T21:56:06.765Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The viewer creates a blob URL from the selected entry’s blob and fetches that URL for the renderer. - **Rationale:** The inspected manifest and entrypoint show no install-time execution, and the flagged fetch operates on a blob URL created from the selected archive item. The required stylesheet contains ordinary styling rules; no malicious behavior was found. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json points to the viewer entrypoints and contains no lifecycle script section., The CommonJS entrypoint re-exports the viewer loader., The flagged archive fetch reads a blob URL created from the selected archive entry’s blob., The required stylesheet path contains ordinary styling rules. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.11.15. - Review the evidence and your use of @atlaskit/media-viewer@54.11.15 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.
