Keycloak: keycloak: uma policy bypass allows authenticated users to gain unauthorized access to victim-owned resources.

A flaw was found in Keycloak. An authenticated user with the uma_protection role can bypass User-Managed Access (UMA) policy validation. This allows the attacker to include resource identifiers owned by other users in a policy creation request, even if the URL path specifies an attacker-owned resource. Consequently, the attacker gains unauthorized permissions to victim-owned resources, enabling them to obtain a Requesting Party Token (RPT) and access sensitive information or perform unauthorized actions.

Keycloak 安全漏洞

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，该漏洞源于具有uma_protection角色的已验证用户可绕过UMA策略验证，可能导致攻击者在策略创建请求中包含其他用户拥有的资源标识符，从而获得对受害者拥有资源的未经授权权限。
