⚠ Under reviewTypeScript SDK for Cursor agents.
AI Security Review
scanned 15d ago · by lpm-firewall-aiThe inspected credential and PR attribution flows appear consistent with the SDK’s configured Cursor service and do not establish an attack. Because substantial bundled runtime code remains unresolved, a clean verdict is not supported by this review.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Importing the SDK activates its selected runtime entrypoint; the inspected PR attribution helper is called after a pull request is opened.
Impact
The reviewed paths do not establish credential theft or harmful command-output disclosure; incomplete source review prevents a clean conclusion.
Mechanism
The reviewed code uses configured Cursor API endpoints and sends parsed pull request metadata through telemetry. Other bundled behavior remains unresolved.
AI rationale
The inspected credential and PR attribution flows appear consistent with the SDK’s configured Cursor service and do not establish an attack. Because substantial bundled runtime code remains unresolved, a clean verdict is not supported by this review.

Decision evidence
public snapshotAI called this Manual Review at 58.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The manifest routes package imports to CJS, ESM, or bundled runtime files and shows no install lifecycle hook.
- The CJS client reads a saved API key only when its stored backend matches the configured Cursor backend.
- The API client sends its key to its configured backend; the inspected default is a Cursor API host.
- The PR attribution path runs Git and forge queries, parses pull request metadata, and reports it through the SDK telemetry path.
- The inspected runtime excerpts do not establish credential theft or command-output exfiltration.
Evidence against
- Large bundled and chunked runtime files remain only partially reviewed, so the full behavior behind the flagged findings is unresolved.
