Password reset poisoning
Summary: Password reset poisoning is a technique in which an attacker manipulates a vulnerable website into generating a password reset link that points to a domain the attacker controls, letting them steal the secret tokens needed to reset arbitrary users' passwords. PortSwigger says the technique was first documented in 2013 by its Director of Research, James Kettle, and that it works when the URL sent to the user is dynamically generated from controllable input such as the Host header.
What's compelling: The victim receives a genuine reset email from the real website with a valid token tied to their account, so the only thing standing between the attacker and account takeover is whether your reset link is built from input a user can influence, like the Host header.
