CVE-2026-7004: WIT SynApps Runtime reflected XSS in login flow

CVE-2026-7004 · Severity: medium · CVSS 6.1 · Published 2026-10-30

WIT SynApps Runtime is a browser-based application runtime for managing industrial controllers. A pre-authentication reflected cross-site scripting flaw in the login flow allows unauthenticated attackers to inject malicious JavaScript that can harvest login credentials, manipulate the login process, or gain unauthorized access to internal industrial controllers in Cloud RIA deployments without directly exposing the controller to the internet.

Technologies: WIT SynApps Runtime. Vendors: WIT.

Technical details

A reflected XSS vulnerability exists in the /System/Session-1 endpoint where the LINK query parameter is not properly sanitized before being rendered in the login page. The vulnerability requires user interaction (clicking a malicious link) but no authentication, allowing attackers to inject arbitrary JavaScript that executes in the context of the login page. In Cloud RIA scenarios, this can be chained with architectural features to bypass IT/OT network segmentation and gain authenticated access to internal REDY controller APIs.
