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.

Risk Assessment

Untrusted web content can make unauthorized network connections, potentially leading to data leakage or use of the application as a proxy for attacks.

Recommendation

Update WebKitGTK and WPE WebKit to patched versions. Verify that applications handle all request types in the send-request handler.
