Answer
Use DTOs instead of binding directly to entity models.
Expose only allowed fields.
Always validate incoming payloads.
Quick Answer
Over-posting: client sends extra fields that get bound to the model and saved unintentionally (e.g., sending IsAdmin=true and having it bound to the user object). Prevent with: separate DTOs for input (only include fields clients should set), [BindNever] to exclude properties, or explicit model mapping. Never bind domain entities directly to HTTP request bodies in production APIs.
