Comment 1 Ivan Devat 2026-06-23 05:51:55 UTC 
There is no impact of this CVE on pcs-web-ui installations in production. The vulnerable library (ws) is not included in the production bundle. It a transitive dependency of development tooling (react-scripts → jsdom). The application source code does not import ws.
