Summary
An API design flaw in WebKitGTK and WPE WebKit allows untrusted web content to unexpectedly perform IP connections, DNS lookups, and HTTP requests. Applications expect to use the WebPage::send-request signal handler to approve or reject all network requests. However, certain types of HTTP requests bypass this signal handler.
