CVE-2018-11713
WebCore/platform/network/soup/SocketStreamHandleImplSoup.cpp in the libsoup network backend of WebKit, as used in WebKitGTK+ prior to version 2.20.0 or without libsoup 2.62.0, unexpectedly failed to use system proxy settings for WebSocket connections.
Does this matter?
Lower severity and a low EPSS score (1.55%). Track it; it rarely justifies an emergency change on its own.
