It attempts dynamic evaluation after exposing CommonJS globals; no endpoint is recoverable from source without executing it. - **Trigger:** Starting server.js imports src/app.js, which imports the altered route. - **Impact:** Potential arbitrary runtime payload execution in a compatible environment; normal ESM execution likely errors first. - **Evidence paths:** package.json, server.js, src/app.js, playground/src/routes/auth.routes.js, src/commands/init.js, src/utils/fileHelper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T06:50:09.955Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated Function-constructor dynamic code execution - **Rationale:** The scaffold code is otherwise user-invoked project generation, but the hidden runtime payload is a concrete dangerous carrier. Its apparent ESM incompatibility prevents confirmation of an active malicious chain without execution. - **Files touched:** server.js, src/app.js, playground/src/routes/auth.routes.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for:** playground/src/routes/auth.routes.js appends a large obfuscated self-invoking payload after normal route code., Payload assigns global require/module aliases and derives the Function constructor to evaluate hidden strings., The payload is reached on runtime import of the route via src/app.js, not by an explicit scaffold action. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., No clear-text network endpoint or credential-exfiltration path was found., The declared ESM package references undeclared require in the payload, likely failing before its hidden stage under normal execution. ## Public findings ### 1.
