Red Hat
Red Hat rates this Low.
An information disclosure vulnerability exists in Qt Framework's QWebSocket authentication handling within the Qt WebSockets module, where improper handling of authentication credentials or state during WebSocket handshakes allows an unauthenticated remote attacker to expose sensitive information.
Disable unauthenticated WebSocket endpoints or restrict network access to trusted clients via reverse proxy authentication controls until an update can be applied.
