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 source supports ordinary media preview behavior: archive contents are converted to local object URLs and optionally exposed through a custom renderer. The required CSS finding contains presentation rules, and no concrete malicious behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-12T04:06:06.718Z - **Finished:** 2026-10-12T04:06:56.967Z - **Download time:** 1020 ms - **Static scan time:** 1691 ms - **AI review time:** 47538 ms - **Total time:** 50249 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 in the inspected entrypoint, archive preview code, or required CSS finding. The flagged fetch is used to read a local object URL created from the selected archive blob. - **Trigger:** A consumer imports the viewer and opens an archive; custom binary access is invoked by a configured custom renderer. - **Impact:** No credential collection, unrelated network transmission, or install-time behavior was established in the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T04:06:56.967Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The preview creates a browser object URL from the selected archive entry's blob, and the custom renderer receives a function for reading that content. - **Rationale:** The inspected source supports ordinary media preview behavior: archive contents are converted to local object URLs and optionally exposed through a custom renderer. The required CSS finding contains presentation rules, and no concrete malicious behavior was established. ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points consumers to the package's compiled viewer entrypoints., The required CSS finding contains ordinary layout and typography rules., Archive preview reads the selected entry as a blob and creates a local object URL for it., Binary content access is provided to a configured custom renderer for the selected archive item. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.11.12. - Review the evidence and your use of @atlaskit/media-viewer@54.11.12 before allowing it.
