GN-Apex zero-config production runtime SDK
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe package is an analytics SDK and documents its automatic event tracking, but it also enables canvas fingerprinting by default without disclosing that collection in its README. This is suspicious runtime telemetry, not evidence of credential theft or an unrelated collector.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Importing and constructing the SDK in a browser with default configuration starts automatic tracking.
Impact
The service can use the fingerprint with visitor and event data to distinguish or track browsers; the README does not disclose canvas fingerprint collection.
Mechanism
The SDK computes a canvas hash, includes it in event data, and batches events to its analytics endpoint with the project API key.
AI rationale
The package is an analytics SDK and documents its automatic event tracking, but it also enables canvas fingerprinting by default without disclosing that collection in its README. This is suspicious runtime telemetry, not evidence of credential theft or an unrelated collector.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The SDK enables analytics and browser fingerprinting by default.
- It derives a canvas hash and includes it as a fingerprint in analytics event data.
- The SDK sends batched analytics events and the project API key to its analytics endpoint.
- The README describes automatic event tracking and session/visitor identity, but does not disclose canvas fingerprinting.
Evidence against
- The package is an analytics SDK, and the README describes its automatic browser tracking.
- The analytics destination is the package’s own service, and the SDK configuration allows analytics and fingerprinting to be disabled.
- The CLI deployment flow is explicitly invoked by a deploy command and excludes several common environment files from its archive.
