Does this matter?

Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.

Description

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.
