ZITADEL race condition in lockout policy execution

ZITADEL provides identity infrastructure. ZITADEL provides administrators the possibility to define a `Lockout Policy` with a maximum amount of failed password check attempts. On every failed password check, the amount of failed checks is compared against the configured maximum. Exceeding the limit, will lock the user and prevent further authentication. In the affected implementation it was possible for an attacker to start multiple parallel password checks, giving him the possibility to try out more combinations than configured in the `Lockout Policy`. This vulnerability has been patched in versions 2.40.5 and 2.38.3.

ZITADEL 竞争条件问题漏洞

ZITADEL是瑞士ZITADEL开源的一个 Auth0、Firebase Auth、AWS Cognito 以及为容器和无服务器时代构建的 Keycloak 的现代开源替代方案。 ZITADEL 2.40.5之前、2.38.3之前版本存在竞争条件问题漏洞，该漏洞源于攻击者有可能启动多个并行密码检查，从而使他有可能尝试比锁定策略中配置的组合更多的组合。
