Keycloak’s improper input validation allows using email as username

Low severity GitHub Reviewed Published Jun 12, 2024 in keycloak/keycloak • Updated Jun 12, 2024

Package

maven org.keycloak:keycloak-services (Maven)

Affected versions

< 24.0.1

Description

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.
