Vulnerability Title
Missing Authentication on Streaming gRPC Replication Endpoint
来源: CVE Program / CVE List V5
Vulnerability Description
The frontend gRPC server's streaming interceptor chain did not include the authorization interceptor. When a ClaimMapper and Authorizer are configured, unary RPCs enforce authentication and authorization, but the streaming AdminService/StreamWorkflowReplicationMessages endpoint accepted requests without credentials. This endpoint is registered on the same port as WorkflowService and cannot be disabled independently. An attacker with network access to the frontend port could open the replication stream without authentication. Data exfiltration is possible, but only when a configured replication target is correctly configured and the attacker has knowledge of the cluster configuration, as the history service validates cluster IDs and peer membership before returning replication data. The fix was applied per release line: it is present in 1.28.4, 1.29.6, 1.30.4, 1.31.2, and 1.32.0 and later releases on each line. Releases 1.31.0 and 1.31.1 do not contain the fix and are affected. Temporal Cloud is not affected.

Temporal 安全漏洞
来源: 中国国家信息安全漏洞库 CNNVD
Vulnerability Description
Temporal是temporal.io开源的一个持久化执行平台。 temporal存在安全漏洞，该漏洞源于前端gRPC服务器的流式拦截器链未包含授权拦截器，导致配置ClaimMapper和Authorizer时，流式AdminService/StreamWorkflowReplicationMessages端点接受无凭据请求，可能允许具有网络访问权限的攻击者未经身份验证打开复制流，可能导致数据渗漏。
