📝 Summary: A DOM XSS vulnerability was discovered in the file import functionality of the Fizzy application. The vulnerability allowed an attacker to craft a malicious filename that, when previewed by the victim user, would inject a second form submission into the import page. This enabled the attacker to perform actions on the victim's account, such as changing the email address, creating a personal access token, and deleting the account, all using the victim's authenticated session.
