AI Security Review
scanned 3d ago · by lpm-firewall-aiThe CLI findings do not establish malicious command-output exfiltration: build errors are handled locally, and deployment is an explicit command. The default, undocumented canvas fingerprinting is a runtime telemetry concern, so this version should receive a warning.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Importing the browser entry constructs the default client, which starts analytics automatically.
Impact
This enables persistent device identification for analytics without clear documentation of the fingerprinting behavior.
Mechanism
With fingerprinting enabled by default, analytics events may include a canvas fingerprint and device attributes, along with visitor identifiers and page URLs; events go to the configured analytics endpoint.
AI rationale
The CLI findings do not establish malicious command-output exfiltration: build errors are handled locally, and deployment is an explicit command. The default, undocumented canvas fingerprinting is a runtime telemetry concern, so this version should receive a warning.

Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The browser client defaults both analytics and fingerprinting to enabled.
- Analytics event context conditionally includes a canvas fingerprint and device entropy.
- The browser client starts analytics automatically when constructed with tracking enabled; the package exports a module-level client.
- The README documents automatic page, click, error, and session tracking, but does not mention canvas fingerprinting.
- Events are posted to the configured analytics URL with the project key; the source shows no unrelated collector.
- The only declared lifecycle hook is prepublishOnly, which runs a build.
Evidence against
- Automatic analytics are part of the package’s stated SDK behavior, including page views and visitor identity.
- The README says automatic form tracking does not collect field values.
- The CLI deploy action is a separately invoked command, rather than an install-time action.
