CVE-2026-1697Network attack vector

Sensitive cookie exposure via missing security attributes

Published Feb 26, 2026 · Updated Feb 26, 2026

Improper cookie protection in PcVue 12.0.0 through 16.3.3 allows remote attackers to expose session data through web access. The GraphicalData web service and WebClient app create sensitive cookies without Secure and SameSite attributes, so browsers can send them over unencrypted or cross-site requests. Exploitation requires passive user interaction and access to the affected WebVue or web-services deployment; it exposes session data and can affect downstream data integrity but does not interrupt service.
