CVE-2026-1694Network attack vector

Server configuration disclosure via retained HTTP headers

Published Feb 26, 2026 · Updated Feb 26, 2026

Information disclosure in PcVue 12.0.0 through 16.3.3 allows remote attackers to obtain server configuration details via HTTP responses. The deployment leaves default IIS and ASP.NET headers, including X-Powered-By, in WebVue, WebScheduler, TouchVue, and SnapVue responses instead of removing them. Exposure requires the Web and Mobile features to be deployed on IIS; the reported consequence is limited to server-configuration disclosure.
