* [ ] self XSS to Open Redirect

  ```jsx
  I decided to check the site's login (which contains registration through Google)
  I found that you can register with any email without verification
  Here I registered my email associated with Google without verifying the email and put the payload, but here I did not need to steal his cookie so I used
  			<meta http-equiv="Refresh"content="5;url=evil.com">
  I logged into my account via Google
  Once I enter the settings, it directs me to another site
  Thus, you can prevent any user from registering for an account and adjusting the name
  ```

<summary><strong>BOPLA: Broken Object Property Level Authorization</strong></summary>

* [ ] Request manipulation to change user name leads to email change

  ```jsx
  Prevent people from registering with a Google account
  In the beginning, I created an account on the site test.com
   (the site contains a login feature from Google)
  -------------------------------------------
  1. I went to the settings and found the site does not allow changing the email with which you created the account with
  2. I decided to take the request for changing the name and added a parameter called "<email:test@gmail.com>"
  3. You can enter any person's email without authentication
  4. The account email has been changed to the email written above
  5. I logged in again to the site, but from a second browser via Google (test@gmail.com), I was rejected, and I got a Forbidden access
  6. I tried to reset the password I was banned from entering my account permanently.
