Vulnerability Title
Lightdash Scheduled Delivery Webhook URLs Are Not Validated, Allowing Server-Side Request Forgery
Vulnerability Description
Lightdash stores the webhook URL supplied with a scheduled delivery and later posts to it from sendWebhook in packages/backend/src/clients/GoogleChat/GoogleChatClient.ts and in packages/backend/src/clients/MicrosoftTeams/MicrosoftTeamsClient.ts. In affected versions both call fetch on the stored URL directly. The validatePublicHttpUrl helper in packages/backend/src/utils/ssrfProtection.ts, used for MCP server URLs, is not applied on either path, and the webhook fields carry no server-side URL constraint. A user able to create or trigger a scheduled delivery can therefore direct the server to issue POST requests to private, loopback and link-local addresses, including cloud metadata endpoints, and can distinguish reachable internal services from unreachable ones through the resulting errors. The upstream response is never returned to the requester; on a failure status its body is written to the server log instead. Version 1.146.4 routes both clients through postSchedulerWebhook from packages/backend/src/utils/schedulerWebhookValidation rather than calling fetch directly.

Lightdash 服务端请求伪造漏洞
Vulnerability Description
Lightdash是Lightdash公司开源的一款日志分析支撑系统。 Lightdash 1.146.4之前版本存在服务端请求伪造漏洞,该漏洞源于GoogleChat和MicrosoftTeams客户端中的sendWebhook函数直接对存储的webhook URL发起请求且缺乏服务端URL验证,可能导致攻击者利用计划交付功能向私有、回环和链路本地地址发起POST请求,造成服务端请求伪造。
