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. Source inspection supports a browser media-viewer implementation with no lifecycle hooks or malicious execution path. The scanner's network and CSS findings are package-aligned and non-malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-13T01:19:08.436Z - **Finished:** 2026-09-13T01:19:46.952Z - **Download time:** 1015 ms - **Static scan time:** 1556 ms - **AI review time:** 35945 ms - **Total time:** 38516 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 confirmed malicious attack surface was established. The only relevant runtime network use is loading a user-selected media archive through the configured media client. - **Trigger:** A user opens a media archive in the viewer. - **Impact:** No unconsented file, credential, process, or configuration access was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-13T01:19:46.952Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Fetches the selected archive URL and parses ZIP entries in the browser. - **Rationale:** Source inspection supports a browser media-viewer implementation with no lifecycle hooks or malicious execution path. The scanner's network and CSS findings are package-aligned and non-malicious. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest defines browser library entry points and contains no lifecycle or binary command hook., The flagged archive code only obtains a media-file URL at viewer runtime and passes it to a ZIP reader., The flagged stylesheet is ordinary static CSS. - **Evidence against:** No install-time execution, shell process use, evaluation primitive, credential harvesting, persistence, or self-dependency was found., No fixed external network endpoint or package-controlled data exfiltration path was found. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.8.18. - Review the evidence and your use of @atlaskit/media-viewer@54.8.18 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.
