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 package entry point exposes a lazy-loaded media viewer, and the inspected fetch and analytics behavior fit that purpose. No install-time behavior, credential collection, unrelated endpoint, or other attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-31T03:33:19.948Z - **Finished:** 2026-10-31T03:33:59.649Z - **Download time:** 1531 ms - **Static scan time:** 1963 ms - **AI review time:** 36207 ms - **Total time:** 39701 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 activity supports media viewing and the analytics code reports media-load experience data. - **Trigger:** Media viewing and media-load success events during normal use. - **Impact:** No malicious impact identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T03:33:59.649Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The viewer loads media content from its supplied source and records media-file experience metadata. - **Rationale:** The package entry point exposes a lazy-loaded media viewer, and the inspected fetch and analytics behavior fit that purpose. No install-time behavior, credential collection, unrelated endpoint, or other attack behavior 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 identifies a media viewer and points to its CommonJS entry point., The entry point exports a lazy-loaded MediaViewer component., Runtime analytics records a media-file experience with feature flags and file attributes when media loads., Archive viewing fetches the supplied source to read its binary content. - **Evidence against:** No lifecycle scripts or bin entry were found in the manifest., The inspected entry point contains no network or filesystem actions., The network and filesystem references inspected serve media viewing; no unrelated collector or credential flow was identified. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.12.3. - Review the evidence and your use of @atlaskit/media-viewer@54.12.3 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.
