GHSA-4vc8-pg5c-vg4x: Keycloak's improper input validation allows using email as username

June 12, 2024

Keycloak allows the use of email as a username and doesn’t check that an account with this email already exists. That could lead to the unability to reset/login with email for the user. This is caused by usernames being evaluated before emails.
