SEC627 / CLAUDE-READ ​

SEC627 flags shared committed Claude settings when permissions.allow contains the exact bare tool token Read.

Why It Matters ​

Bare Read grants unreviewed filesystem read authority without narrowing access to repository-scoped paths.

Trigger Shape ​

This rule matches parsed Claude settings JSON where permissions.allow contains the exact string Read.

How To Fix ​

Replace bare Read with a narrower reviewed permission pattern such as Read(./docs/**), or remove broad read access from the shared Claude settings file.
