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. Static inspection found no malicious behavior. The flagged fetch is part of user-facing archive preview behavior, and the required CSS finding contains presentation rules. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-10T06:27:39.043Z - **Finished:** 2026-10-10T06:28:25.059Z - **Download time:** 1014 ms - **Static scan time:** 1628 ms - **AI review time:** 43373 ms - **Total time:** 46016 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 flagged network call retrieves content for a selected archive item through the viewer’s custom-renderer path. - **Trigger:** A consumer renders an archive item with a custom renderer and requests its binary content. - **Impact:** This supports normal archive preview behavior; no separate exfiltration or install-time behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:28:25.059Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The viewer fetches that item’s source and converts the response to a blob. - **Rationale:** Static inspection found no malicious behavior. The flagged fetch is part of user-facing archive preview behavior, and the required CSS finding contains presentation rules. ### 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 identifies a web media viewer and points its public entrypoints to bundled library code., The flagged archive code fetches a selected archive item’s source only when a custom renderer requests its binary content, then returns the response as a blob., The required CSS finding contains ordinary presentation rules. - **Evidence against:** The inspected manifest contains no lifecycle scripts or self-dependency., The inspected archive fetch is tied to rendering a selected archive item; no unrelated endpoint or credential transfer appears in the cited behavior. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.10.2. - Review the evidence and your use of @atlaskit/media-viewer@54.10.2 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.
