Windmill SQL Injection and Authorization Bypass

SQL injection in Windmill workflow orchestration platform versions 1.276.0 through 1.603.2 enables authenticated attackers to escalate privileges to administrator and achieve remote code execution. The vulnerability exists in folder ownership management functionality where the owner parameter lacks input sanitization, allowing extraction of JWT signing secrets and administrative user identifiers to forge admin tokens. Publicly available exploit code exists (GitHub POC by Chocapikk), and EPSS risk assessment is critical given the low-complexity remote attack vector requiring only low-privilege authentication. Vendor-released patch: version 1.603.3.

Authorization bypass in Windmill 1.56.0-1.614.0 enables Operator role users to escalate privileges to remote code execution. Operators can bypass documented role restrictions via unprotected backend API endpoints to create/modify scripts, flows, and apps, then execute arbitrary code through the jobs API. Public exploit code exists (GitHub: Chocapikk/Windfall). EPSS data unavailable, but the low attack complexity (AC:L), network access vector (AV:N), and availability of weaponized POC indicate elevated real-world risk for self-hosted Windmill deployments with Operator-level users.
