Technical details
Mongoid passes unsanitized string-typed query criteria directly to MongoDB as server-side JavaScript expressions without neutralization. An unauthenticated remote attacker able to control query parameters can inject arbitrary code that executes in the database engine context, bypassing application logic. This results in unintended data disclosure, document selection manipulation, and potential denial of service via resource exhaustion.
