AI Security Review
scanned 4d ago · by lpm-firewall-aiThe flagged credential flow sends a user-submitted OneSource key to the OneSource API for validation. Runtime analytics is disclosed, has an opt-out, and the reviewed events contain usage metadata rather than argument values or tool output.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Key validation occurs on an explicit connect-submit request; analytics runs during CLI service use and tool calls by default.
Impact
No credential theft or harmful behavior was identified. The reviewed telemetry records usage metadata rather than tool argument values or output.
Mechanism
The key is sent as a bearer credential to the OneSource API for validation. Analytics sends tool and service usage events to the configured analytics endpoint, with an opt-out setting.
AI rationale
The flagged credential flow sends a user-submitted OneSource key to the OneSource API for validation. Runtime analytics is disclosed, has an opt-out, and the reviewed events contain usage metadata rather than argument values or tool output.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The connect handler accepts an API key supplied in the request body and validates it against the OneSource API.
- The validation request sends the candidate key to the package's own OneSource API host.
- Runtime analytics uses OneSource's analytics endpoint by default and supports disabling collection with ONESOURCE_ANALYTICS=false.
- Tool-call analytics records usage metadata and input parameter names, not parameter values or tool output.
- The package describes analytics as anonymous usage statistics and provides an opt-out.
