## Overview

Windmill CE and EE versions 1.276.0 through 1.603.2 contain an SQL injection vulnerability in the folder ownership management functionality that allows authenticated attackers to inject SQL through the owner parameter. An attacker can use the injection to read sensitive data such as the JWT signing secret and administrative user identifiers, forge an administrative token, and then execute arbitrary code via the workflow execution endpoints.

## Affected

- `windmill_ce_community_edition >= 1.276.0 <= 1.603.2`
- `windmill_ee_enterprise_edition >= 1.276.0 <= 1.603.2`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
