## Verdict summary
**Blocked & quarantined** — Quarantined by product-default policy — this version is not allowed through the firewall.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 0.14.1
- **Selected version is latest:** Yes
- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

OpenSSF/OSV advisory MAL-2026-10160 confirms this npm version as malicious. Package name typosquats the popular rollup-plugin-polyfill-node and copies its README verbatim to bait installs. On require() of the main entry (dist/index.js), the module decodes base64 blobs to reconstruct the strings 'npm install svgson-lite --no-save --silent --no-audit --no-fund' and the module name 'svgson-lite', spawns the install via child\_process.spawn (stdio ignored, windowsHide true), and on process close...
