CVE-2026-47107 WRITEUP HIGH WRITEUP
Windmill < 1.703.2 Incorrect Default Permissions in nsjail Configuration
Windmill prior to 1.703.2 contains an incorrect default permissions vulnerability in nsjail sandbox configuration files where /etc is bind-mounted without read-write restrictions, allowing authenticated users to write arbitrary entries to /etc/hosts, /etc/resolv.conf, and /etc/ssl/certs/ca-certificates.crt from within script execution sandboxes. Attackers can exploit persistent poisoned entries across all subsequent script executions on the same worker pod to redirect hostnames, intercept DNS queries, perform transparent HTTPS man-in-the-middle attacks, and intercept WM_TOKEN JWTs to gain workspace-admin access to other users' workspaces.

CVE-2026-22683 WRITEUP HIGH WRITEUP
Windmill < 1.615.0 Operator Role Missing Authorization Checks RCE
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.
CVSS 8.8
CVE-2026-23696 WRITEUP CRITICAL WRITEUP
Windmill < 1.603.3 File Ownership Handling SQLi RCE
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.

CVE-2026-26964 WRITEUP LOW WRITEUP
Windmill <=1.634.6 - Info Disclosure
Windmill is an open-source developer platform for internal code: APIs, background jobs, workflows and UIs. Versions 1.634.6 and below allow non-admin users to obtain Slack OAuth client secrets, which should only be accessible to workspace administrators. The GET /api/w/{workspace}/workspaces/get_settings endpoint returns the slack_oauth_client_secret to any authenticated workspace member, regardless of their admin status. It is expected behavior for non-admin users see a redacted version of workspace settings, as some of them are necessary for the frontend to behave correctly even for non-admins. However, the Slack configuration should not be visible to non-admins. This is a legacy issue where the setting was stored as a plain value instead of using $variable indirection, and it was never added to the redaction logic. This issue has been fixed in version 1.635.0.

Windmill 1.380.0 - Improper Restriction of Excessive Authentication Attempts in HTTP Request Handler
A vulnerability was found in Windmill 1.380.0. It has been classified as problematic. Affected is an unknown function of the file backend/windmill-api/src/users.rs of the component HTTP Request Handler. The manipulation leads to improper restriction of excessive authentication attempts. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. Upgrading to version 1.390.1 is able to address this issue. The patch is identified as acfe7786152f036f2476f93ab5536571514fa9e3. It is recommended to upgrade the affected component.
