Summary

Daytona: Cross-tenant data leak in notification WebSocket gateway via unverified organizationId join

Details

Summary

A cross-tenant authorization flaw in Daytona's notification WebSocket gateway allowed any authenticated user to subscribe to another organization's realtime notification channel and passively receive that organization's events.

Impact

The notification gateway's JWT handshake joined a client-supplied organization identifier to the corresponding notification room without verifying that the authenticated user was a member of that organization. As a result, an authenticated user could receive another organization's realtime sandbox, snapshot, volume, and runner events, including data carried in those events. This is a cross-tenant confidentiality break. It required a valid account and knowledge of the target organization id (a non-secret UUID); no elevated privileges were needed. The API-key authentication path was not affected.

The affected component is the Daytona API service (the apps/api NestJS application). It is distributed through Daytona's repository releases and container images for self-hosted deployments; it is not published as a Go or npm package, so the advisory will not surface through go get or npm dependency tooling.
