CVE-2026-67540

MediumCVSS 6.5/10Last modified Nov 13, 2026

Description

Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.70, get_workflow_template / get_node_template fetches a template by ID with no visibility / author / shared_with predicate, so any authenticated user can read (and use) any other tenant's private (visibility=specific_users) template — including its full node/edge graph and the email addresses it was shared with. The list endpoint enforces visibility correctly; the single-item get/use paths do not. This issue has been patched in version 0.0.70.
