# No Rate-limit on Invite User

***

## Description :

* Rate limiting is a strategy for limiting network traffic. It puts a cap on how often someone can repeat an action within a certain timeframe – for instance, trying to log in to an account.

***

## Steps To Reproduce

* 1 - Go to `https://target.com/`
* 2 - Navigate to `Invite User` option and Enter the `victim's email`
* 3 - Send invite & `Intercept` the Request
* 4 - Send the request to `Intruder` & clear payload positions
* 5 - Apply payload type as `null payload` and payload count as 100
* 5 - Click on `Start attack` after applying the threads
* 6 - The victim will get huge number of emails

***

## Impact :

* If the company is using any email service software API(such as AWS,GCP..etc) or some tool that has been bought for the emails being sent on the support domain, the rate limit can result in `financial loss` and it can also `slow down your services` as huge/mass mails will `lead to disruption of data` that original user might send or the quota that has been bought might be exhausted.

***

## Mitigation -

* 1 - IP Based Blocking
* 2 - Captcha
* 3 - Firewall
* 4 - Reducing the number of API requests

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kathan19.gitbook.io/howtohunt/rate-limit/no-rate-limit-on-invite-user.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
