AI Security Review
scanned 23h ago · by lpm-firewall-aiThe flagged bundle initializes PostHog telemetry against an external analytics host and enables autocapture by default when Studio is used. This is suspicious runtime telemetry because the reviewed package source does not disclose the collection, though an opt-out exists and the initializer shows no credential exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A deployment enables Studio and a user opens it, mounting the analytics component.
Impact
Browser interaction telemetry may be sent to PostHog. The reviewed code does not show this initializer sending credentials or server environment values.
Mechanism
The bundled PostHog SDK initializes against https://us.posthog.com with autocapture enabled by default; a telemetry-disabled flag suppresses initialization.
AI rationale
The flagged bundle initializes PostHog telemetry against an external analytics host and enables autocapture by default when Studio is used. This is suspicious runtime telemetry because the reviewed package source does not disclose the collection, though an opt-out exists and the initializer shows no credential exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The bundled PostHog configuration enables autocapture by default and uses https://us.i.posthog.com.
- When the Studio analytics component mounts, it initializes PostHog unless the browser is Brave or telemetry is disabled.
- The CloudDeployer copies Studio assets only when Studio is enabled; its constructor defaults Studio to false.
- The package manifest has build, test, and lint scripts, with no install lifecycle hook.
Evidence against
- Studio telemetry has a MASTRA_TELEMETRY_DISABLED opt-out.
- The reviewed analytics initializer does not show credentials or server environment values being sent.
