CVE-2022-39229 is an improper authentication vulnerability in Grafana versions before 8.5.14 and 9.1.8. Grafana permits authentication using either a username or an email address, but did not prevent one account's username from matching another account's email address. An attacker can register a username equal to an existing victim user's email address, causing subsequent login attempts using that email address to resolve to the attacker-controlled account. Because the victim's password does not match that account, the victim cannot authenticate.
