As a result, users could be deanonymized by crafted web sites via a WebSocket connection.

jdstrand | webkit receives limited support. For details, see https://wiki.ubuntu.com/SecurityTeam/FAQ#webkit webkit in Ubuntu uses the JavaScriptCore (JSC) engine, not V8
mdeslaur | It looks like this requires a new API introduced in libsoup 2.62.0 to be fixed. We are not going to backport the new API. Marking releases older than bionic as ignored.
