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.

Coder 2.30.0 至 2.34.8（不含 2.34.8）版本中存在一个授权绕过漏洞，该漏洞位于 provisioner daemon 的 DownloadFile gRPC 处理程序中。已认证的 provisioner daemon 可利用此漏洞下载其他组织的 Terraform 模块缓存归档文件。若攻击者拥有组织范围（org-scoped）的 provisioner 密钥并知晓特定文件的 UUID，即可检索模块源代码，从而暴露基础设施拓扑结构或其中嵌入的敏感凭证。
