Lightdash version 0.1024.6 allows users with the necessary permissions, such as Administrator or Editor, to create and share dashboards. A dashboard that contains HTML elements which point to a threat actor controlled source can trigger an SSRF request when exported, via a POST request to /api/v1/dashboards//export. The forged request contains the value of the exporting user’s session token. A threat actor could obtain the session token of any user who exports the dashboard. The obtained session token can be used to perform actions as the victim on the application, resulting in session takeover.

Multiple stored cross-site scripting (“XSS”) vulnerabilities in the markdown dashboard and dashboard comment functionality of Lightdash version 0.1024.6 allows remote authenticated threat actors to inject malicious scripts into vulnerable web pages. A threat actor could potentially exploit this vulnerability to store malicious JavaScript which executes in the context of a user’s session with the application.

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.
