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 source shows normal viewer entrypoints, styling, and user-invoked retrieval of archive content. The network finding is consistent with the package's viewer functionality, and no concrete attack surface was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-10T06:27:09.210Z - **Finished:** 2026-10-10T06:27:35.424Z - **Download time:** 1512 ms - **Static scan time:** 1827 ms - **AI review time:** 22874 ms - **Total time:** 26214 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. Inspected network use belongs to the archive viewer's requested content retrieval. - **Trigger:** A caller or custom archive renderer invokes the binary-content callback for an archive entry. - **Impact:** Retrieves the selected archive content for display; no malicious behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T06:27:35.424Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The callback fetches that entry's source and returns the response as a blob. - **Rationale:** Inspected source shows normal viewer entrypoints, styling, and user-invoked retrieval of archive content. The network finding is consistent with the package's viewer functionality, and no concrete attack surface was found. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points to browser-facing CommonJS and ESM viewer entrypoints and marks compiled CSS as side effects., The required CSS finding is ordinary presentation styling., The archive viewer fetches the selected archive entry's source only when its binary-content callback is invoked. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.9.4. - Review the evidence and your use of @atlaskit/media-viewer@54.9.4 before allowing it.
