Quick assessment

Affected

Red Hat Red Hat Build of Keycloak

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Keycloak 的组件中，认证会话处理存在一个缺陷。该问题源于系统在标准认证流程与重置凭证流程之间切换时，未能验证当前认证器是否适用于当前的认证流程。已认证的攻击者可通过在凭证重置过程中触发竞态条件，将其自身的成功认证状态与另一用户的会话进行关联。这可能导致攻击者获得对受害者账户的完全访问权限，并修改其密码。

Vulnerability Title

Keycloak-services: keycloak-services: account takeover via authentication race using reset-credentials path

Source: CVE Program / CVE List V5

Vulnerability Description

A flaw was found in the authentication session handling of the keycloak-services component in Keycloak. The issue occurs because the system fails to verify if an authenticator is valid for the current authentication flow when switching between the standard authentication path and the reset credentials path. An authenticated attacker can exploit this by triggering a race condition during the credential reset process to associate their successful authentication state with another user's session. This can result in the attacker gaining full access to the victim's account and changing their password.
