Vulnerability Title
Keycloak-services: keycloak-services: name-only group claims let same-name groups satisfy path-specific group policies
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the group policy provider of Keycloak authorization services, which is used to manage fine-grained access control to resources. The issue occurs when the system evaluates group-based policies using tokens that only contain group names rather than full paths. If two groups in different parts of the organization share the same name, a user in the unauthorized group can be mistaken for a member of the authorized group. This can allow a user to gain unauthorized access to protected resources they should not be able to reach.

Keycloak 授权问题漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Keycloak是Keycloak组织开源的一款身份认证与权限管理平台。 Keycloak存在授权问题漏洞，该漏洞源于授权服务的组策略提供程序在评估基于组的策略时使用仅包含组名而非完整路径的令牌，导致不同组织部分中的同名组被混淆，将未授权用户误认为授权组成员，可能允许用户未经授权访问受保护资源。
