Executive brief
Novu is a notification platform that manages integrations with third-party providers. Before version 3.18.0, users with access to one environment could delete, modify, or reconfigure integrations from other environments within the same organization, potentially compromising notification delivery or exposing provider credentials. The 3.18.0 patch only partially addresses this for API-key authentication while leaving dashboard-session behavior vulnerable.
Technical details
An access control vulnerability in Novu's integration mutation endpoints (remove-integration, update-integration, auto-configure-integration, set-integration-as-primary) fails to consistently enforce environment boundaries when looking up integrations by integrationId and organizationId. Attackers with API key or session access to one environment can target integration identifiers from other environments in the same organization. Version 3.18.0 scopes environment-key API authentication but deliberately retains cross-environment behavior for dashboard sessions, leaving the remediation incomplete.
