CyberRota Analysis
AI-GeneratedLightdash is vulnerable due to improper validation of webhook URLs, allowing users to create scheduled deliveries that can direct the server to send POST requests to internal and private addresses, potentially exposing sensitive information about internal services. The impact includes the ability to probe internal network configurations and access cloud metadata endpoints, which could lead to further exploitation. Organizations using affected versions of Lightdash should prioritize remediation to mitigate the risk of internal service exposure and potential data breaches.

Original NVD 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.
