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 required stylesheet finding is ordinary CSS, and the flagged fetch is scoped to a selected archive entry provided to a custom renderer. The inspected manifest and source show no concrete attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-10-10T06:27:30.992Z - **Finished:** 2026-10-10T06:27:56.457Z - **Download time:** 1272 ms - **Static scan time:** 1803 ms - **AI review time:** 22390 ms - **Total time:** 25465 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 in the inspected source. The flagged network request is tied to loading a selected archive entry for a custom renderer. - **Trigger:** A consumer displays an archive entry using a configured custom renderer and that renderer requests its binary content. - **Impact:** This supports the media viewer's archive preview behavior; no unrelated data collection or external destination was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:27:56.457Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The callback fetches the selected entry source and returns its response body as a blob. - **Rationale:** The required stylesheet finding is ordinary CSS, and the flagged fetch is scoped to a selected archive entry provided to a custom renderer. The inspected manifest and source show no concrete attack behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest identifies the expected package and release., The required CSS finding contains ordinary layout and typography rules., Archive entry fetching occurs only through the selected custom renderer's content callback., The inspected package source contains no concrete malicious behavior. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.9.8. - Review the evidence and your use of @atlaskit/media-viewer@54.9.8 before allowing it.
