A flaw was found in keycloack before version 8.0.0. The owner of placeholder.org domain can setup mail server on this domain and knowing only name of a client can reset password and then log in. For example, for client name test the email address will be service-account-test@placeholder.org.
Weakness
The product uses hard-coded constants instead of symbolic names for security-critical values, which increases the likelihood of mistakes during code maintenance or security policy change.
