@posterna/next@0.1.3
Next.js integration for Posterna: verify AI agents and crawlers and apply policy.
AI Security Review
scanned 6d ago · by lpm-firewall-aiThis is undisclosed runtime telemetry: counters are enabled by default and transmit aggregated request and policy data when the integration has a site key. The reporting is limited and can be stopped with `counters: false`, so this warrants a warning rather than a publish block.
Static reason
No blocking static signals were detected.
Trigger
Creating the integration and handling requests with counters enabled and a site key supplied through options or POSTERNA_SITE_KEY.
Impact
Posterna receives aggregate usage and request classification data without the README disclosing the telemetry; disabling counters or omitting a site key prevents transmission.
Mechanism
The counters aggregate request verdict and policy-related fields, then POST them to the configured base URL, defaulting to https://posterna.com/v1/ingest, using the site key as a bearer token.
AI rationale
This is undisclosed runtime telemetry: counters are enabled by default and transmit aggregated request and policy data when the integration has a site key. The reporting is limited and can be stopped with `counters: false`, so this warrants a warning rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package creates its counters automatically unless callers set `counters: false`, and passes the environment and site key into that client.
- When a site key is present, the counters client sends aggregated request verdict, agent, purpose, path-group, action, and count data with the key as a bearer token.
- The counters client posts to the package’s default Posterna endpoint; the README does not disclose this runtime telemetry.
Evidence against
- The counter payload contains aggregated buckets rather than request bodies or credentials.
- Without a site key, the client keeps the buckets local and discards them instead of transmitting them.
- The manifest has no install lifecycle scripts, and the package’s entry points are a Next.js integration.
