TREK is a collaborative travel planner. Prior to 3.3.0, the get_trip_summary tool in server\/src\/mcp\/tools\/trips.ts is registered for scoped OAuth MCP tokens without requiring trips:read and returns core trip summary data regardless of the delegated scopes. A token granted only an unrelated capability, such as weather:read, can receive trip metadata, member email addresses from server\/src\/services\/tripService.ts, itinerary days, and accommodations for every trip accessible to the token’s user. Cross-user trip authorization remains enforced, but the missing scope check defeats the consented least-privilege boundary and exposes trip content and third-party contact information to an MCP client that was not authorized to read it. This issue is fixed in version 3.3.0.<\/p>\n","protected":false},"excerpt":{"rendered":"
