In versions prior to 4.14.9.5, the password-based login endpoint uses TypeScript type assertion without runtime validation, allowing an unauthenticated attacker to pass a MongoDB query operator object (e.g., {\"$ne\": \"\"}) as the password field. This NoSQL injection bypasses the password check, enabling login as any user including the root administrator.
