CVE-2026-1010
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA stored cross-site scripting (XSS) vulnerability exists in the Altium Workflow Engine due to missing server-side input sanitization in workflow form submission APIs. A regular authenticated user can inject arbitrary JavaScript into workflow data. When an administrator views the affected workflow, the injected payload executes in the administrator’s browser context, allowing privilege escalation, including creation of new administrator accounts, session token theft, and execution of administrative actions.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Altium On Prem Enterprise Server installationLocate the Altium Enterprise Server installation directory or check installed programs list for 'Altium On Prem Enterprise Server'Affected if The software is not installed - not affected
-
Verify installed version is 8.0.1Check the Altium server version through the administration interface or by inspecting version files in the installation directoryAffected if Installed version is exactly 8.0.1 - potential exposure to this vulnerability
-
Confirm Workflow Engine module is enabledLog into Altium Enterprise Server as administrator and navigate to System Settings or Modules to verify the Workflow Engine feature is activeAffected if Workflow Engine is enabled - the vulnerability can be triggered
-
Check for existing workflows with form submissionsAccess the Workflows section in the administration panel and review any active workflows that include form submission stepsAffected if There are workflows with form submissions - potential existing XSS payloads may be present
-
Inspect API endpoint accessibilityReview API documentation or network traffic to confirm workflow form submission endpoints (typically /api/workflow/submit or similar) are exposed to authenticated usersAffected if Form submission APIs are accessible to regular (non-admin) users - attack vector is viable
A user is affected if they run Altium On Prem Enterprise Server version 8.0.1 with the Workflow Engine enabled and form submission APIs accessible to regular authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement server-side input validation and output encoding/sanitization for all workflow form submission API endpoints to neutralize malicious script payloads before storage and upon rendering.
