Alert meAnalysisAIv1 – Mar 12, 2026
Stored XSS in Altium Workflow Engine allows authenticated users to inject malicious scripts into workflow forms that execute with administrator privileges when viewed. An attacker can exploit this to escalate privileges, create new admin accounts, steal session tokens, and perform arbitrary administrative actions. No patch is currently available for the on-premises enterprise server deployment.
Earlier versions of this analysis (1)
A 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. [CVSS 8.0 HIGH]
RemediationAI
Monitor vendor advisories for a patch. Implement output encoding and Content Security Policy headers. Restrict network access to the affected service where possible.

DescriptionCVE.org
A 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.
Executive ViewAI
CVE-2026-1010 presents notable security risk, a cross-site scripting vulnerability rated CVSS 8.0. Attackers could inject malicious scripts to steal user sessions, credentials, or perform actions on behalf of authenticated users. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Implement Content-Security-Policy headers; (2) Enable HttpOnly and SameSite cookie attributes; (3) Deploy WAF XSS/CSRF rules.

Priority Score
Attack Technique
Cross-Site Scripting occurs when an application accepts untrusted data and sends it to a web browser without proper validation or encoding.
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
