Host header
Several times the back-end trust the Host header to perform some actions. For example, it could use its value as the domain to send a password reset. So when you receive an email with a link to reset your password, the domain being used is the one you put in the Host header.Then, you can request the password reset of other users and change the domain to one controlled by you to steal their password reset codes. WriteUp.
Note that it's possible that you don't even need to wait for the user to click on the reset password link to get the token, as maybe even spam filters or other intermediary devices/bots will click on it to analyze it.
Session booleans
Some times when you complete some verification correctly the back-end will just add a boolean with the value "True" to a security attribute your session. Then, a different endpoint will know if you successfully passed that check. However, if you pass the check and your sessions is granted that "True" value in the security attribute, you can try to access other resources that depends on the same attribute but that you shouldn't have permissions to access. WriteUp.
Register functionality
Try to register as an already existent user. Try also using equivalent characters (dots, lots of spaces and Unicode).
Takeover emails
Register an email, before confirming it change the email, then, if the new confirmation email is sent to the first registered email,you can takeover any email. Or if you can enable the second email confirming the firt one, you can also takeover any account.
