AI Security Review
scanned 4d ago · by lpm-firewall-aiThe flagged API key is sent to OneSource’s API for validation as part of the connect flow. Default runtime analytics reports usage metadata, uses hashed identifiers, and has a documented opt-out; no malicious behavior was found.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
API-key validation follows a connect submission; analytics and update checks run when the CLI server starts.
Impact
No credential exfiltration or other malicious impact was identified in the reviewed flows.
Mechanism
The submitted key is sent to the configured OneSource API base. Analytics sends usage metadata to its configured dashboard and can be disabled with ONESOURCE_ANALYTICS=false.

Decision evidence
public snapshotAI called this Clean at 92.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The connect flow validates a submitted API key against the configured OneSource API base, defaulting to api.onesource.io.
- Runtime analytics reports tool metadata and input parameter names; session identifiers are hashed before reporting.
- Analytics uses the OneSource dashboard endpoint by default, supports ONESOURCE_ANALYTICS=false, and the CLI reports its analytics status.
- The CLI checks the npm registry for this package’s latest version.
Evidence against
- Analytics is enabled by default and sends runtime events to the dashboard when the server runs.
- The package makes routine network requests to OneSource and the npm registry.
