## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

zyncmap@0.0.0 advertises itself as an SVG sanitization/minification utility, but index.js exports an undocumented function getPlugin() that, when invoked, performs an HTTP GET against the anonymous paste host https://www.jsonkeeper.com/b/3P9BF and passes the response's \`model\` string field directly to eval(). Content at that paste URL is attacker-mutable, so any consumer that calls the exported getPlugin() executes arbitrary attacker-controlled JavaScript in the installer's Node.js process. The README and ~80% of index.js implement plausible SVG helpers as cover; the remote-fetch+eval export and a misleading \`bearrtoken: "logo"\` header are appended separately and not mentioned in package documentation. This is a backdoor: a hidden code path giving the publisher persistent remote code execution against any consumer who reaches the export.
