resend-cli@2.14.0
The official CLI for Resend
AI Security Review
scanned 3mo ago · by lpm-firewall-aiStatic hints conflate local credential-store commands and bounded CLI telemetry with exfiltration. Direct inspection found no lifecycle execution or concrete malicious chain.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User invokes the resend CLI.
Impact
No credential, command-output, file-harvesting, persistence, or install-time malicious behavior confirmed.
Mechanism
Resend API client, local credential storage, and anonymous command telemetry.
AI rationale
Static hints conflate local credential-store commands and bounded CLI telemetry with exfiltration. Direct inspection found no lifecycle execution or concrete malicious chain.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with high false-positive risk.
Evidence for AI clean decision
- Package exposes only a user-invoked CLI binary; no install lifecycle hook is declared.
- Telemetry records bounded CLI metadata and supports opt-out.
- Credential handling uses the local Resend config path and OS credential stores.
- Child-process use is limited to local credential-store utilities.
Evidence against
- No source evidence sends user credentials, command output, or harvested files to a remote receiver.
- Network use is package-aligned: Resend API operations and PostHog CLI telemetry.
- Default telemetry creates a local anonymous identifier, but its payload schema excludes credential/config data.
