Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 8 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 54.11.10 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 behavior is consistent with a media viewer: its archive renderer fetches content for a caller-selected custom renderer, and its CSS provides presentation styles. The scanner's CSS analysis limitation is explained by inspected styling content and does not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-11T04:48:53.621Z - **Finished:** 2026-10-11T04:49:31.822Z - **Download time:** 1027 ms - **Static scan time:** 1622 ms - **AI review time:** 35551 ms - **Total time:** 38201 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 package entrypoints or archive viewer behavior. - **Trigger:** A consuming application imports the viewer; archive content is fetched when the custom renderer invokes its binary-content callback. - **Impact:** No confirmed attack surface was established by these behaviors. - **Review source:** ai\_review - **Reviewed:** 2026-10-11T04:49:31.822Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected code fetches the supplied archive-entry source for rendering and creates a local object URL from preview data; no credential collection or unrelated outbound destination was established. - **Rationale:** The inspected behavior is consistent with a media viewer: its archive renderer fetches content for a caller-selected custom renderer, and its CSS provides presentation styles. The scanner's CSS analysis limitation is explained by inspected styling content and does not establish malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes library entrypoints and marks compiled CSS as side-effectful styling., The required CSS finding is ordinary presentation styling., The archive viewer fetches a source only when a caller-provided custom renderer requests binary content., The archive viewer creates an object URL from a blob for local preview. ## Affected versions and remediation This report applies to @atlaskit/media-viewer@54.11.10. - Review the evidence and your use of @atlaskit/media-viewer@54.11.10 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. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 2. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 3. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 4. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** dist/cjs/styleWrappers.compiled.css - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() The manifest exposes library entrypoints and marks compiled CSS as side-effectful styling. Public source snippet (untrusted): ```json "main": "dist/cjs/index.js", "module": "dist/esm/index.js", "module:es2019": "dist/es2019/index.js", "types": "dist/types/index.d.ts", "sideEffects": [ "*.compiled.css" ], ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** dist/cjs/styleWrappers.compiled.css - **Public source:** [View source]() The required CSS finding is ordinary presentation styling. Public source snippet (untrusted): ```text ._11q75a80{background:linear-gradient(180deg,#101214,rgba(14,22,36,0)) no-repeat} ._151kfhey._151kfhey h1{font:var(--ds-font-body,normal 400 14px/20px "Atlassian Sans",ui-sans-seri ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** dist/cjs/viewers/archiveSidebar/archive-viewer-base.js - **Public source:** [View source]() The archive viewer fetches a source only when a caller-provided custom renderer requests binary content. Public source snippet (untrusted): ```javascript _context3.next = 1; return fetch(src); case 1: return _context3.abrupt("re ``` ### 8. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 90.0% - **Path:** dist/cjs/viewers/archiveSidebar/archive-viewer-base.js - **Public source:** [View source]() The archive viewer creates an object URL from a blob for local preview. Public source snippet (untrusted): ```javascript blobWithMimeType = new Blob([blob], { type: mimeType }); src = URL.createObjectURL(blobWithMimeType); if (!i ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 49 - **Optional dependencies:** 0 - **Peer dependencies:** 4 - **Development dependencies:** 30 - **Published dependency-graph edges:** 53 ### Published dependency entries - @atlaskit/analytics-next ^12.6.0 (Dependency) - @atlaskit/button ^25.4.0 (Dependency) - @atlaskit/code ^20.0.0 (Dependency) - @atlaskit/css ^1.1.0 (Dependency) - @atlaskit/form ^18.2.0 (Dependency) - @atlaskit/heading ^8.0.0 (Dependency) - @atlaskit/icon ^38.0.0 (Dependency) - @atlaskit/icon-file-type ^8.3.0 (Dependency) - @atlaskit/icon-lab ^7.11.0 (Dependency) - @atlaskit/media-client ^39.1.0 (Dependency) - @atlaskit/media-client-react ^7.0.0 (Dependency) - @atlaskit/media-common ^14.6.0 (Dependency) - @atlaskit/media-document-viewer ^2.2.0 (Dependency) - @atlaskit/media-state ^4.0.0 (Dependency) - @atlaskit/media-svg ^4.0.0 (Dependency) - @atlaskit/media-ui ^31.3.0 (Dependency) - @atlaskit/menu ^11.0.0 (Dependency) - @atlaskit/motion ^9.3.0 (Dependency) - @atlaskit/platform-feature-experiments ^0.3.0 (Dependency) - @atlaskit/platform-feature-flags ^2.2.0 (Dependency) - @atlaskit/portal ^7.0.0 (Dependency) - @atlaskit/primitives ^22.5.0 (Dependency) - @atlaskit/react-compiler-gating ^0.2.0 (Dependency) - @atlaskit/side-navigation ^13.3.0 (Dependency) - @atlaskit/spinner ^20.4.0 (Dependency) - @atlaskit/textfield ^10.2.0 (Dependency) - @atlaskit/theme ^28.2.0 (Dependency) - @atlaskit/tmp-editor-statsig ^230.0.0 (Dependency) - @atlaskit/tokens ^20.4.0 (Dependency) - @atlaskit/tooltip ^24.4.0 (Dependency) - @atlaskit/ufo ^2.0.0 (Dependency) - @babel/runtime ^7.0.0 (Dependency) - @codemirror/language 6.10.8 (Dependency) - @codemirror/language-data 6.5.1 (Dependency) - @codemirror/state 6.5.1 (Dependency) - @codemirror/view 6.36.2 (Dependency) - @compiled/react ^1.0.2 (Dependency) - @kenjiuno/msgreader ^1.2.6 (Dependency) - @lezer/highlight 1.2.1 (Dependency) - deep-equal ^1.0.1 (Dependency) - fflate ^0.8.1 (Dependency) - mime ^2.4.6 (Dependency) - perf-marks ^1.5.0 (Dependency) - react-error-boundary ^3.1.3 (Dependency) - react-focus-lock ^2.9.5 (Dependency) - react-loadable ^5.1.0 (Dependency) - react-scrolllock ^5.0.1 (Dependency) - unzipit ^1.3.0 (Dependency) - use-callback-ref ^1.2.3 (Dependency) - @emotion/react ^11.7.1 (PeerDependency) - react ^18.2.0 (PeerDependency) - react-dom ^18.2.0 (PeerDependency) - react-intl ^5.25.1 || ^6.0.0 || ^7.0.0 (PeerDependency) ## Package metadata - **Package:** @atlaskit/media-viewer - **Ecosystem:** npm - **Version:** 54.11.10 - **License:** Apache-2.0 - **Version published:** 2026-10-09T21:52:29.175Z - **Package first seen:** 2026-06-30T23:45:17.760Z - **Package last seen:** 2026-11-04T20:05:06.482Z - **Known versions:** 101 - **Latest version:** 54.12.9 - **Appeal under review:** No - **Description:** MediaViewer is Atlassian's powerful solution for viewing files on the web.
