Associated Vulnerability

Title: Windmill < 1.615.0 Operator Role Missing Authorization Checks RCE (CVE-2026-22683)
Description:Windmill versions 1.56.0 through 1.614.0 contain a missing authorization vulnerability that allows users with the Operator role to perform prohibited entity creation and modification actions via the backend API. Although Operators are documented and priced as unable to create or modify entities, the API does not enforce the Operator restriction on workspace endpoints, allowing an Operator to create and update scripts, flows, apps, and raw_apps. Since Operators can also execute scripts via the jobs API, this allows direct privilege escalation to remote code execution within the Windmill deployment. This vulnerability has existed since the introduction of the Operator role in version 1.56.0.

Description

Windmill versions 1.276.0 through 1.603.2 contain an authorization bypass vulnerability in the folder management API endpoints. The endpoints for creating, deleting, and managing folder ownership do not enforce role-based access control for operator-level users. In Windmill, operators are restricted users intended to only execute existing scripts, but due to missing server-side authorization checks, operators can create folders, manage folder permissions, and access owner management endpoints. This bypass serves as the prerequisite for exploiting CVE-2026-23696 (SQL injection via folder addowner) enabling full privilege escalation from operator to super admin with remote code execution.
