CVE-2026-1010 is a high-severity stored cross-site scripting (XSS) vulnerability that exists in the Altium Workflow Engine. This vulnerability arises due to missing server-side input sanitization in workflow form submission APIs. An authenticated user can exploit this flaw to inject arbitrary JavaScript into the workflow data.
When an administrator views the affected workflow, the injected payload executes in the administrator’s browser context. This can lead to serious consequences, such as privilege escalation, which includes the ability to create new administrator accounts, steal session tokens, and execute unauthorized administrative actions.
The CVSS score for this vulnerability is 8, indicating a high severity level, which necessitates immediate attention from security teams. The potential impact of this vulnerability is significant, making it crucial for organizations to prioritize remediation efforts.
Organizations should address this vulnerability in their priority patch cycle to prevent unauthorized access and potential exploitation.
The vulnerability was published on January 15, 2026, and has since been analyzed for its impact and potential exploitability. Currently, there are no known exploits in the wild, but the risk remains due to the nature of the vulnerability.
Vulnerability Details
The vulnerability allows attackers to exploit the Altium Workflow Engine due to inadequate input validation, specifically regarding the workflow form submission APIs. The vulnerability type classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-269 (Privilege Escalation) underscores the critical nature of this issue.
The CVSS score for this vulnerability is 8.0, indicating high severity. This score reflects the potential impact on confidentiality, integrity, and availability.
The affected product is the Altium on-prem_enterprise_server, specifically version 8.0.1. The vulnerability was published on January 15, 2026, and it is categorized as analyzed in its current status.
Technical Analysis
The root cause of this vulnerability is the lack of server-side input validation, which allows an authenticated user to inject harmful scripts into the workflow data. The attack vector is through the network, and the complexity is low, requiring only basic privileges (low) and user interaction (required).
Once the malicious script is injected, it can have severe impacts on confidentiality, integrity, and availability, as the attacker could execute actions in the context of the administrator's session.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized administrative access, data breaches, and exploitation of the application for further attacks. The urgency for remediation is high, given the CVSS score of 8, indicating a critical need for organizations to patch this vulnerability immediately.
The blast radius is significant, as an attacker gaining administrative privileges could have complete control over the affected system, leading to further exploitation across the network. Organizations must prioritize this vulnerability in their security assessments and remediation processes.
