@grum-os/cli@0.3.22
Keep a repository on the design contract reviewed in Grum: a local drift check, review requests, Cursor hooks and an MCP server.
AI Security Review
scanned 23d ago · by lpm-firewall-aiNo install-time attack or command-output exfiltration was established; the outbound report contains repository identifiers and summarized findings. The explicit agent setup path modifies Cursor configuration, which merits a capability warning.
Static reason
One or more suspicious static signals were detected.
Trigger
Run the setup flow and accept Cursor setup, or explicitly run the init command for Cursor.
Impact
Cursor agents in that repository can use Grum’s configured hooks and MCP tools.
Mechanism
The initializer writes Cursor hook and MCP configuration and manages Grum’s own rule file.
AI rationale
No install-time attack or command-output exfiltration was established; the outbound report contains repository identifiers and summarized findings. The explicit agent setup path modifies Cursor configuration, which merits a capability warning.
Evidence
grum.mjs.cursor/hooks.json.cursor/mcp.json.cursor/rules/grum.mdc
Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest exposes grum.mjs as a CLI for repository checks, Cursor hooks, and an MCP server.
- The indicated Cursor rule path is recognized as a Grum-owned rule and excluded from contract rule results.
- The setup flow asks whether to configure Cursor, and the setup command dispatches to that flow.
- The Cursor initializer writes repository hook and MCP configuration files and manages Grum’s rule file.
- The check report sends project, branch, commit, and summarized finding details to Grum.
- The flagged process use invokes Git through execFileSync, without shell execution.
Evidence against
- The manifest declares no install lifecycle scripts; the configuration behavior requires running the CLI setup or init command.
- The inspected source provides no evidence that command output is sent to the service.
