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 the package entrypoints, the flagged archive viewer behavior, and the required CSS path. The fetch supplies archive-entry content to a custom renderer, while the flagged CSS contains ordinary styling; no malicious behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-10T06:27:48.117Z - **Finished:** 2026-10-10T06:28:07.988Z - **Download time:** 1546 ms - **Static scan time:** 1519 ms - **AI review time:** 16806 ms - **Total time:** 19871 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 network call is part of the archive viewer's selected-entry content callback. - **Trigger:** A custom archive renderer requests binary content for the selected archive entry. - **Impact:** No harmful effect is established by the inspected code. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:28:07.988Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The callback fetches the entry source and returns its blob to the renderer. - **Rationale:** Inspected the package entrypoints, the flagged archive viewer behavior, and the required CSS path. The fetch supplies archive-entry content to a custom renderer, while the flagged CSS contains ordinary styling; no malicious behavior was found. ### Review decision - **Verdict:** Clean - **Confidence:** 89.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points to ordinary CommonJS and ESM viewer entrypoints and declares the compiled CSS as a side effect., The flagged CSS excerpt contains presentation rules for a gradient and heading typography., The archive viewer fetches the selected archive entry only through its custom renderer's binary-content callback. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.8.38. - Review the evidence and your use of @atlaskit/media-viewer@54.8.38 before allowing it.
