PatchTheCVECVE-2026-23696: Windmill CE and EE versions 1.276.0 through 1.603.2 contain an SQL injection vulnerability in the folder owner
CVE-2026-23696 is a critical-severity flaw (CVSS 9.9) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- Critical severity
- EPSS top 4%: very likely to be exploited
- CISA SSVC: public proof of concept
A fixed release or distro patch exists.
