Account Takeover In shopware/core

Description

Shopware 6's password recovery link does not expire after email change

Summary

When a customer changes their email address after requesting a password reset, the old password reset link (tied to the previous email) remains valid. An attacker with access to the old email inbox is potentially able to reset the customer’s password even after the user changes their email address.
