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 manifest has no lifecycle scripts, the required CSS is styling, and the flagged fetch operates on the selected archive entry's generated source URL. The inspected source provides no evidence of malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-10T06:27:19.961Z - **Finished:** 2026-10-10T06:28:02.569Z - **Download time:** 1258 ms - **Static scan time:** 1657 ms - **AI review time:** 39692 ms - **Total time:** 42608 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 network request reads a generated URL for a selected archive entry for custom rendering. - **Trigger:** A consumer uses the media viewer to open an archive and selects an entry handled by a custom renderer. - **Impact:** No attacker-controlled external destination or harmful effect was established from the inspected code. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:28:02.569Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The renderer fetches the selected entry's source URL and converts the response to a blob. - **Rationale:** The manifest has no lifecycle scripts, the required CSS is styling, and the flagged fetch operates on the selected archive entry's generated source URL. The inspected source provides no evidence of malicious behavior. ### 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 points consumers to the compiled CommonJS entrypoint and contains no scripts key., The required CSS file contains ordinary styling declarations., Archive entries are read from the selected entry as a blob; a custom renderer fetches the generated source URL and reads its blob., No concrete attack behavior was identified in the inspected source. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.9.6. - Review the evidence and your use of @atlaskit/media-viewer@54.9.6 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.
