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 points to library entry points, and the required CSS finding is ordinary styling. The archive fetch is conditional on selected archive content and an explicitly configured custom renderer, with no evidence of unrelated network or file activity. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-10T06:28:15.553Z - **Finished:** 2026-10-10T06:28:42.569Z - **Download time:** 1552 ms - **Static scan time:** 1840 ms - **AI review time:** 23623 ms - **Total time:** 27016 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 inspected archive code exposes entry fetching to a configured custom renderer during selected-file rendering. - **Trigger:** A selected archive entry is rendered and a configured custom renderer is selected. - **Impact:** This supports the viewer's custom rendering flow; no confirmed malicious behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:28:42.569Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The renderer receives a function that fetches the entry source and returns its blob. - **Rationale:** The inspected manifest points to library entry points, and the required CSS finding is ordinary styling. The archive fetch is conditional on selected archive content and an explicitly configured custom renderer, with no evidence of unrelated network or file activity. ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points to viewer library entry points and marks compiled CSS as side-effect assets; the required CSS file contains styling rules., Archive content is fetched only when a selected file has a configured custom renderer, and the fetch uses that archive entry's source. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.11.9. - Review the evidence and your use of @atlaskit/media-viewer@54.11.9 before allowing it.
