CVE-2026-42572 Â (opens in a new tab)How to fix?
Upgrade github.com/hatchet-dev/hatchet/api/v1/server/handlers/v1/tasks to version 0.83.39 or higher.
Overview
Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key in the GET /api/v1/stable/dags/tasks endpoint via improper tenant checks in the listTasksByDAGIds() function. An attacker can access sensitive task metadata belonging to other tenants by supplying a valid tenant UUID and DAG UUID for which they are not authorized. This is only exploitable if the attacker has an account on the instance and knows both the victim tenant's UUID and a DAG UUID belonging to that tenant.
Workaround
This vulnerability can be mitigated by restricting account creation to trusted domains using the SERVER_AUTH_RESTRICTED_EMAIL_DOMAINS setting or by ensuring the API is not exposed to untrusted networks.
