CVE-2026-54324Network attack vector

Cross-tenant event disclosure via unverified organization join

Published Jun 23, 2026 · Updated Jun 23, 2026

Incorrect authorization in Daytona before 0.185.0 allows remote authenticated users to read cross-tenant notification events. The notification gateway's JWT handshake joins a client-supplied organizationId to its notification room without verifying the user's membership in that organization. A valid account and knowledge of the target organization's non-secret UUID are required; exposed events can contain sandbox, snapshot, volume, and runner data.
