@clerk/clerk-js@6.42.2
Clerk JS library
AI Security Review
scanned 1d ago · by lpm-firewall-aiThe package is identified as Clerk's SDK, and the inspected telemetry is disclosed, limited to development instances, and disableable. However, its event payload includes a configured secret-key prefix sent to the telemetry endpoint, which warrants a warning.
Static reason
One or more suspicious static signals were detected.
Trigger
SDK telemetry records an event while running against a development instance; telemetry is enabled by default unless disabled.
Impact
A partial secret-key value is disclosed to the telemetry service; the inspected code does not send the full key in this payload.
Mechanism
The event payload includes the first 16 characters of the configured secret key, then is sent in a POST to the telemetry endpoint.
AI rationale
The package is identified as Clerk's SDK, and the inspected telemetry is disclosed, limited to development instances, and disableable. However, its event payload includes a configured secret-key prefix sent to the telemetry endpoint, which warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The SDK telemetry code adds the first 16 characters of a configured secret key to its event payload.
- Telemetry events are POSTed to https://clerk-telemetry.com/v1/event.
- Telemetry is enabled for development instances by default, though it can be disabled and the SDK displays a telemetry notice with an opt-out link.
Evidence against
- Only a 16-character prefix is included; the inspected code does not send the full configured secret key in this telemetry payload.
- The notice says telemetry applies to development instances and links to opt-out instructions; CLERK_TELEMETRY_DISABLED also disables it.
- The package metadata identifies the expected Clerk JavaScript repository and package directory.

Copied Package Dependency Bridge
Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.
