Until a patch is available, restrict access to the affected functionality to trusted users only and monitor for suspicious activity related to folder ownership management.
Description
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.
