It runs server-provided JavaScript with access to require after the exported helper is invoked. - **Trigger:** A CommonJS consumer calls getPlugin() and invokes the returned function. - **Impact:** Remote operator can execute arbitrary Node.js code in the consumer process. - **Evidence paths:** package.json, src/index.cjs, src/index.mjs, src/index.d.ts, README.md, bin/svgcraft.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-29T17:36:01.778Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** HTTPS fetch with disabled TLS verification followed by dynamic code execution - **Attack narrative:** An undocumented CommonJS-only getPlugin helper retrieves data from workconfig.vercel.app with rejectUnauthorized:false and passes it to new Function together with require. The fetched response therefore becomes executable Node.js code in the caller's process. The helper is absent from the ESM API, types, and documentation, concealing this behavior behind an SVG utility package. - **Rationale:** The concealed remote payload loader is concrete arbitrary code execution, not required for the documented SVG functionality. Absence of install hooks limits automatic activation but does not remove the malicious backdoor. - **Files touched:** src/index.cjs - **Network endpoints:** https://workconfig.vercel.app ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** src/index.cjs exports undocumented getPlugin., getPlugin fetches https://workconfig.vercel.app., It disables TLS certificate validation., Response data is executed with new Function(require, data). - **Evidence against:** package.json has no lifecycle hooks., src/index.mjs and CLI contain only SVG utilities., README.md and index.d.ts omit getPlugin. ## Public findings ### 1.
