Vulnerability Title
Keycloak: keycloak: brute-force protection bypass in ciba flow
Vulnerability Description
A flaw was found in Keycloak, an open-source identity and access management solution. When a user account is temporarily locked due to repeated failed login attempts, an attacker with valid client credentials can exploit the Client-Initiated Backchannel Authentication (CIBA) flow to bypass this brute-force protection. This allows continued authentication attempts and token issuance even when the account should be locked, potentially enabling further unauthorized access attempts.

Vulnerability Title
Keycloak 安全漏洞
Vulnerability Description
Keycloak是Keycloak开源的一种开源身份和访问管理解决方案。 Keycloak存在安全漏洞,该漏洞源于当用户账户因重复登录失败尝试被临时锁定时,具有有效客户端凭据的攻击者可利用客户端发起的反向信道认证流程绕过暴力破解保护,可能导致即使在账户应被锁定时仍能继续身份验证尝试和令牌发放,从而可能进行进一步的未经授权访问尝试。
