A flaw was found in Keycloak. In certain conditions, this issue may allow a remote unauthenticated attacker to block other accounts from logging in.
The product contains an account lockout protection mechanism, but the mechanism is too restrictive and can be triggered too easily, which allows attackers to deny service to legitimate users by causing their accounts to be locked out.
