Title
Windmill Labs Windmill - Missing Authorization
Summary
A missing authorization vulnerability in Windmill Labs Windmill through 1.783.0 allows authenticated operators to write job progress and read job metrics for any job in the workspace regardless of ownership. The job_metrics handlers accept no authorization extractor, bypassing workspace-level access controls. An operator can monitor sensitive job execution data and inject misleading progress for jobs they do not own.

Title
Windmill Labs Windmill - Missing Authorization
Summary
A missing authorization vulnerability in Windmill Labs Windmill through 1.783.0 allows any authenticated workspace member to overwrite any resource type schema via the update_resource_type endpoint. The endpoint omits the administrator permission check that the corresponding delete_resource_type endpoint enforces. An attacker with workspace member privileges can corrupt resource type definitions, breaking workflows that depend on them.

Title
Windmill Labs Windmill - Information Disclosure
Summary
An information disclosure vulnerability in Windmill Labs Windmill through 1.783.0 allows any authenticated workspace member to read legacy ownerless draft scripts that contain plaintext resource credentials. Drafts with a null owner email bypass ACL enforcement and are returned to any workspace member who queries the drafts endpoint. Sensitive credentials stored in these drafts are exposed across ACL boundaries.

Title
Windmill < 1.603.3 File Ownership Handling SQLi RCE
Summary
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.

Title
Windmill < 1.615.0 Operator Role Missing Authorization Checks RCE
Summary
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.

Title
Windmill Labs Windmill - Missing Authorization
Summary
A missing authorization vulnerability in Windmill Labs Windmill through 1.783.0 allows authenticated operators to write job progress and read job metrics for any job in the workspace regardless of ownership. The job_metrics handlers accept no authorization extractor, bypassing workspace-level access controls. An operator can monitor sensitive job execution data and inject misleading progress for jobs they do not own.

Title
Windmill Labs Windmill - Missing Authorization
Summary
A missing authorization vulnerability in Windmill Labs Windmill through 1.783.0 allows any authenticated workspace member to overwrite any resource type schema via the update_resource_type endpoint. The endpoint omits the administrator permission check that the corresponding delete_resource_type endpoint enforces. An attacker with workspace member privileges can corrupt resource type definitions, breaking workflows that depend on them.

Windmill Labs Windmill - Information Disclosure
Summary
An information disclosure vulnerability in Windmill Labs Windmill through 1.783.0 allows any authenticated workspace member to read legacy ownerless draft scripts that contain plaintext resource credentials. Drafts with a null owner email bypass ACL enforcement and are returned to any workspace member who queries the drafts endpoint. Sensitive credentials stored in these drafts are exposed across ACL boundaries.

Windmill < 1.603.3 File Ownership Handling SQLi RCE
Summary
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.

Title
Windmill < 1.615.0 Operator Role Missing Authorization Checks RCE
Summary
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.
