Vulnerability Title
Dgraph Alpha group stores can be replaced via unauthenticated external snapshot import
Source: CVE Program / CVE List V5
Vulnerability Description
Dgraph is an open source distributed GraphQL database. Prior to version 25.3.5, Dgraph Alpha exposes the RPCs used for external snapshot import on the public gRPC port `:9080` without authentication or authorization. As a result, an unauthenticated network client can open `StreamExtSnapshot` and send Badger stream data to the target group’s store. In addition, the receiver calls `Prepare()` before processing the stream. This operation deletes and replaces the existing DB data. Version 25.3.5 patches the issue.

Vulnerability Title
Dgraph 授权问题漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Dgraph是Dgraph组织开源的一个具有图形后端的水平可扩展分布式 GraphQL 数据库。 Dgraph 25.3.5之前版本存在授权问题漏洞，该漏洞源于在公共gRPC端口`:9080`上暴露用于外部快照导入的RPC且无身份验证或授权，可能导致未经身份验证的网络客户端打开`StreamExtSnapshot`并向目标组存储发送Badger流数据，接收者在处理流之前调用`Prepare()`会删除并替换现有数据库数据。
