savant-code@0.0.36
Multi-Agent AI Coding Assistant with ECHO Protocol
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe launcher conditionally sends runtime telemetry containing a local home-directory path and update error details to an environment-configured analytics host. This is a privacy risk warranting a warning; the behavior is conditional and does not establish a malicious exfiltration campaign.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A CLI launch encounters a failed update download while a PostHog API key and host are configured in the environment.
Impact
The configured analytics host can associate update failures with a local account path and receive diagnostic details.
Mechanism
The launcher posts an event to the configured host's /capture/ endpoint, including the home-directory path as distinct_id and download error details.
AI rationale
The launcher conditionally sends runtime telemetry containing a local home-directory path and update error details to an environment-configured analytics host. This is a privacy risk warranting a warning; the behavior is conditional and does not establish a malicious exfiltration campaign.
Evidence
launcher.js
Network endpoints1
Host configured by SAVANT_CODE_POSTHOG_HOST or NEXT_PUBLIC_POSTHOG_HOST_URL
Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Launcher telemetry is enabled when PostHog API key and host environment variables are present.
- The telemetry payload includes the user's home directory in distinct_id and sends an error message, version, platform, and architecture.
- A failed binary download automatically calls the telemetry function with error and download diagnostics.
Evidence against
- The manifest declares no install, preinstall, or postinstall hook.
- Telemetry is conditional on environment-configured API key and host; the launcher does not hard-code a telemetry destination.
- Downloaded updates are staged and installation is offered for user approval.
