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 opens the HTML page and clicks Publish, it transmits their npm bearer token and selected package payload through a third-party Worker. This creates a credential and package-data exfiltration path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-14T03:44:36.390Z - **Finished:** 2026-09-14T03:45:30.823Z - **Download time:** 766 ms - **Static scan time:** 14 ms - **AI review time:** 53652 ms - **Total time:** 54433 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 opens the HTML page and clicks Publish, it transmits their npm bearer token and selected package payload through a third-party Worker. This creates a credential and package-data exfiltration path. - **Trigger:** Opening index.html and clicking Publish after supplying a token and file. - **Impact:** The proxy can receive npm credentials and the full selected package contents. - **Evidence paths:** app.js, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-14T03:45:30.823Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Proxying an authenticated package upload through a third-party endpoint. - **Attack narrative:** The page presents itself as an npm publisher, collects an npm token and package file, then routes the authenticated PUT request through a third-party Cloudflare Worker in normal browser use. The proxy receives both the Authorization header and serialized file attachments, enabling credential and package-data capture. The page also embeds a prefilled npm token. - **Rationale:** This is a concrete credential and data-exfiltration path through an undisclosed third-party proxy. It is user-triggered rather than install-time, but the token-routing behavior warrants blocking publication. - **Network endpoints:** https://dawn-salad-6ee1.vihaanb0715.workers.dev, https://registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The browser publisher sends the supplied npm bearer token through a third-party Cloudflare Worker rather than directly to npm., The same request includes all selected package-file contents, allowing the proxy to receive private package data., The HTML contains a prefilled npm authentication token., The manifest has no install lifecycle hook; the risky behavior runs when the page is opened and Publish is clicked., The HTML embeds a prefilled npm authentication token in the password input. - **Evidence against:** No install, preinstall, or postinstall script is declared., No child-process execution, filesystem persistence, or dynamic code loading was found. ## Affected versions and remediation This report applies to @vbansal67/official-publisher@1.0.0. - Avoid installing @vbansal67/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.
